Shizuma Ikushima

Shizuma is a veterinary student and Shohei's older brother.

He ended his relationship with his ex-girlfriend, Yuka, after she cheated on him. He identifies as bisexual. Later on, Shizuma graduates from veterinary school and begins his employment as a veterinarian, but his job leaves him with less time to spend with Minato. However, the two agree to move in together. Diligent and charismatic, Shizuma puts a lot of effort into his work and does not give up despite the difficulties he initially encounters in his new work environment.
