Who Is RnBoi? Aya Nakamura's First Signing Took 'J'assume' to No. 3 in France

RnBoi is a French R&B singer and producer, and the first artist Aya Nakamura signed to her own label, a signing she revealed in April 2025. His new single, 'J'assume', came out on Friday 16 October and entered France's official singles chart, the SNEP Top Singles dated 23 October, at No. 3. A year earlier his breakthrough, 'Mon bébé', had entered the same chart at No. 6.

'J'assume' is French for 'I own it'. The verb assumer looks like the English 'assume', but it means to own something and stand by it in front of others. RnBoi uses it in two ways about a love he calls toxic: as an order to the woman he is singing to, and as a confession about himself.

RnBoi and Aya Nakamura: from her label to 'Mon bébé' and 'J'assume'

RnBoi grew up in Nemours, a small town south of Paris. Aya Nakamura named him in an interview with Billboard France published on 24 April 2025: she had signed him a few months earlier, and nobody knew yet. He was the first name on her new independent label. When the magazine Numéro reported the signing on 5 May 2025, he had more than 800,000 monthly listeners on Spotify. He now has 5.1 million.

The jump came with 'Mon bébé', released on 24 October 2025. It got as high as No. 2 on the SNEP chart and topped Spotify's French daily list, with 755,202 streams on its best day. SNEP certified it diamond on 8 January 2026, less than three months after release, and by 25 October 2026 it had passed 230 million Spotify streams. A remix with the Nigerian singer Ayra Starr followed on 20 February 2026.

This year he released a duet with Aya Nakamura, 'J'PENSE À TOI', on 26 March and the album 'My Eyes Only – Flashback' the next day; the album went platinum on 3 September. Three more of his singles went diamond in France this year: 'Avec moi' with Nono La Grinta and 'BTRD' in June, and 'Elle voulait' in August. In March Rabanne made him the face of its 1 Million fragrance in France. At the NRJ Music Awards in Cannes on 23 October he was up for French-language male breakthrough of the year; the award went to Anyme. On 23 November he plays L'Olympia in Paris, and four days later he releases 'Après Minuit', a 12-track project on which 'J'assume' is the second song.

The 'J'assume' lyrics, and what RnBoi owns up to

RnBoi starts with a goodbye that does not quite take. He tells a former lover not to message him, recalls that she told him to let go when he left home, and insists he has not changed. She should remember what they did to each other, he says, and forget that they ever missed each other.

In the chorus he blames her first. What she really likes, he tells her, is when it turns toxic and they hurt each other, so she should own that. He could treat her as the queen of his heart and do all of it without ever loving her, so she should try not to fall. Then he turns the charge on himself: “J'aime trop quand ça devient toxic” (I like it too much when it turns toxic), and the title follows twice, now in the first person. He adds that he likes the way she talks when she tells him where it hurts.

His second verse is softer. This time she should not come back and should protect her heart; they warned each other before any regrets; he saw her eyes and tells her not to cry. Three lines in a row begin the same way and say that whatever hurts heals afterwards, fades in the end and leaves them a little better. The section before the last chorus is the hardest on her. He thought she was crazy, decides it is more than that, wishes she gets better, better without him, and accuses her of not wanting to heal at all, only to go back. The song closes on half-heard background ad-libs that the lyric sites write down differently; the clearest words, 'combien de fois' (how many times), come back again and again.

He blames her taste for the drama, then admits to sharing it, and the verse in the middle reads like advice he cannot follow. None of it is sung as a warning.

The soft guitar sound of 'J'assume'

For its first 15 seconds 'J'assume' is a guitar, treated with chorus and echo, and a few sung yeahs. RnBoi's verse starts at 15.7 seconds in the clip, and our sound classifier labels it sad at first, then tender and soul music.

About 40 seconds in, the chorus arrives. The loudness reading rises from 0.44 to 0.71, and the classifier's top guesses switch to reggae and rhythm and blues: the same guitar now sits on a beat with a lilt. After the second verse, the section before the last chorus starts at about 1:35, and its last line, at 1:58, is where the track gets loudest, and it stays that way through the final chorus from about 2:02. After 2:30 only faint ad-libs remain over the guitar as it plays out, and the last 16 seconds of the clip are street sounds. Our key estimate is B major.

The distributor lists three songwriters: RNBOI, also credited as producer, and two whose credit names include an instrument, 'Max à la guitare' ('Max on guitar') and 'Seny au piano' ('Seny on piano'). The clip was directed by Antoine Wibeaux and produced by PATERN. Two of the top comments compare him to Justin Bieber, and two others welcome the change of style, saying RnBoi is finally making R&B and that it suits him.

Where 'J'assume' climbed in its first ten days

RnBoi put the hook out before the song. On YouTube he posted a short teaser on 12 October and, on 13 October, a second one built on the opening line of the chorus. The single went live at midnight Paris time on 16 October, and the clip at 18:00 that evening.

On Spotify's daily chart in France it opened at No. 7 with 275,175 streams, slipped to No. 15 the next day, then climbed to No. 3 on 24 and 25 October. Its first week put it at No. 8 on the weekly chart with 1,603,789 streams. On Shazam, the app people open to identify a song playing near them, it rose in France from No. 49 on 18 October to No. 2 on 26 October, behind only Karol G's 'BbY WOW'. It is No. 3 on Apple Music in France and No. 8 on YouTube's weekly song chart there, and on 27 October YouTube listed its clip fifth in France's trending music and third in Belgium's. By 27 October the clip had 2,479,349 views and 34,908 likes.

Outside France, the Spotify numbers are smaller. Its highest place in Belgium was No. 30, and it is nowhere on Spotify's global daily top 200, where the song at No. 200 on 25 October had 1,021,520 streams; the best French day for 'J'assume' was 278,598.

The two songs above 'J'assume' on Spotify France

On the official chart 'J'assume' started higher than 'Mon bébé' did, and 'Après Minuit' follows in a month. But the top of France's daily chart is crowded. On 25 October Vacra and La Rvfleuze's 'Fille à Papa' had 430,364 streams on its 36th day at No. 1, and Tiakola's 'Mélo décalé' had 301,612, against 256,788 for 'J'assume'.

We expect the 'J'assume' clip to pass 5 million YouTube views by 27 November, the day 'Après Minuit' comes out, and the song not to top Spotify's French daily list before then: on 25 October 'Fille à Papa' was drawing about 174,000 more streams a day.
