 Main Characters

 Shu Yu, 22 years old (CV: Xian Ta Wu Tong)

A woman who gives the false impression of being "quiet" may actually be filled with an incredibly wild and unrestrained inner world of eroticism. In order to produce something worthwhile, she often controls her inner turmoil. However, even the tip of the iceberg that is revealed is admirable. She is either a genius or simply a rampage of hormones.

She has an unusually high enthusiasm for depicting the feelings between girls, but in public, she hides it as simply choosing this subject matter to make a living. However, those who know her well can still glimpse some of her true self from the emotions that overflow from her.

 Lu Xi, 20 years old (CV: She Slows Down)

Energetic women who give off a "lively" vibe are actually quite afraid of loneliness.

She appears to be a very outgoing and fulfilled person, but behind the scenes she's a voice actress active on online platforms and a seasoned anime and manga enthusiast. Just like the "older sister" who doesn't want people to know she writes R17.9 yuri novels, she also doesn't want people to know she's an anime and manga otaku who enjoys online voice acting.

She harbors a surprising flutter of excitement for her "older sister" whom she has after blending into a family, but she buries this feeling deep behind her daily poker face for fear that her "older sister" will find out and feel disgusted.

 Biscuit, 36 years old (CV: Ruiza)

A mature and experienced older sister, she is a key editor who specifically liaises with Shuyu. She often has a headache dealing with how to drastically cut out content that is inadvertently leaked from her writing, but she also admits that her writing is indeed quite useful, it's just a pity that it's not for other websites.

Although she had always harbored resentment towards Shu Yu and nagged like a senior colleague, her care and compromise were evident to all her colleagues—it's just that she couldn't remember names, could she please fix that sooner rather than later!
