Hinata and Mizuki, step-siblings, became lovers and began living together right after graduating from high school. As time passes, Mizuki goes on to graduate school, while Hinata enters the workforce. However, stepping into different worlds gradually causes a rift to form between them. Furthermore, the presence of Hinata’s boss, Kamiki Kyota, begins to cast a shadow over their relationship. Hinata finds his heart wavering toward Kamiki, who is strict yet caring toward his juniors, and Mizuki does not miss this subtle change. “Student” and “working adult”—a small yet significant divide stands between them.

Reviews
season 2 started cute but focused too much on another character (vertical series)
Overall: 30 episodes about 2 minutes each. Watched on GagaOOLala https://www.gagaoolala.com/en/verticals/7753/that-nerd-is-my-brother-in-law-s2-2026Note: they are step brothers not brother in laws
What I Liked
- good start
- interesting that the younger guy was working in an office, while the older guy was in grad school
- realistic struggle when people in a relationship are at different stages of school vs work
Room For Improvement
- needed to focus on the 2 leads
- watch episodes 1-4, 15, 28-30
- too many flashbacks
