A Twisted Cohabitation with a Woman Brought Home by a Live-in Boyfriend... 'My Boyfriend's Female Friend: The Two of Us Falling Apart' to Stream Exclusively on StellaJean from May 27!

studio15 Inc., a company operating in the short-form video domain centered on TikTok, will exclusively stream its new short drama, 'My Boyfriend's Female Friend: The Two of Us Falling Apart,' on the short drama platform 'StellaJean,' operated by BookLive Co., Ltd., starting Monday, May 27, 2026.

■ Highlights
This work is a distorted triangle love story adapted from the popular manga '#Edge ~My Boyfriend's Female Friend~,' originally serialized on BookLive's original female manga label 'COMIC Étoile.' It portrays the communal life that begins when a woman, claiming to be the boyfriend's 'female friend,' moves in with a happily cohabiting couple.

The cast features talented actors who vividly portray the raw 'front and back' of human nature. The lead roles are played by Kanami Takasaki, active as a gravure idol and actress; Yurina Kawaguchi, who gained attention on the Korean audition show 'Girls Planet 999'; and Takuya Nakahara, a promising actor who appeared in the studio15 production 'I Can Hear the Love of the Complicated Aki-kun.' The talented cast intensely embodies the one-upmanship between women over a single man, the dual nature of humans, and the madness born from obsession.

The production is handled by studio15, which has created numerous popular works, including the short drama account 'Drama Mitai da' with over 500 million total views on social media. With overwhelming directorial skill and a sense of speed cultivated in the short-form video field, it draws viewers deep into the story's abyss.

■ Synopsis
For Manami Miyamoto (Kanami Takasaki), a wedding planner who has just started living with her beloved boyfriend, Yuki Takamatsu (Takuya Nakahara), every day was supposed to be the beginning of a long-dreamed-of happiness. However, one night, Yuki brings home an unknown woman. 'Nice to meet you. I'm Yuki's female friend, and I'll be living with you from today.' Ignoring a bewildered Manami, the woman—Seika Akimori (Yurina Kawaguchi)—casually enters the apartment, opens the fridge, and lies on the sofa. Citing stalking as her reason, she asks to stay for a while. For some reason, Yuki can't refuse, as if she has something on him. Manami wants to kick her out, but she can't. As if mocking Manami's turmoil, Seika gradually settles into the home. Is she really just a 'female friend'? What is the reason Yuki can't say no? And is the man she believed to be the 'ideal boyfriend' for three years really the person she knows? At the end of a cohabitation swirling with lies, jealousy, and obsession, what 'form of happiness for herself' will Manami find?

■ Lead Cast Comments
Kanami Takasaki (as Manami Miyamoto): 'When I read the manga, I was on the edge of my seat with the messy developments, but it was so interesting that I came to love this work. Thinking about Manami's feelings was frustrating at times, but the teamwork was great, and filming was a lot of fun. Please watch this amazing work we've created!'

Yurina Kawaguchi (as Seika Akimori): 'Seika's life is filled with days and emotions I've never experienced in my own. When I first read the script, I was so shocked and frankly felt I wanted to live her unconventional life. It's a work where you can experience various forms of love, so I hope you enjoy watching it.'

Takuya Nakahara (as Yuki Takamatsu): 'When I first read the script, my impression of Yuki was simply that he's a 'messed-up guy.' The instability and emotional changes that become apparent as the story progresses were very difficult to portray, but also enjoyable. I hope I was able to realistically express human weakness and fragility through the character of Yuki.'
