1. Haruka Tohgoh (27)
She works in the PR department of a home appliance company. She's "Tohgoh the Troll" at work, but a hard bottom when it comes to relationships. One thing leads to another, ending up with Tohgoh becoming friends with benefits with Sayama, her junior at work. But as Sayama's affection (?) for her grows, she finds herself at a loss what to do. On days off, she spends her time shopping or doing housework.
2. Friends With Benefits
3. Change!!
4. Rika Sayama (25)
A new addition to the office in Tohgoh's PR department. Cheerful, wholesome, and all-around lovable. At least, that's how she presents. In reality, she's a freak who likes to take total control in bed. She took a liking to Tohgoh and cut ties with all her other girls. Recently, she started allowing herself to laugh, be cross, and generally be more open in front of Tohgoh. On days off, she spends her time satisfying her desires.
5. Change!!
6. Mutual Feelings?
7. Hitomi Arimura (36)
The current head of the project management department and Tohgoh's former boss. She gave up on love after going through a divorce, but now she's wavering because of Hinami's confession.
8. Yuki Hinami (22)
A new addition to the project management department. She's good at her job but not very friendly and is often misunderstood. Hitomi is her first love and is now fiercely on the attack.
