ヤンパパと天使と俺

Tomohisa is a graduate student who feels drained from daily studying. Additionally, he's secretly gay with no experience in relationships. During these monotonous times, he encountered Kouki, a fellow student of the same age. Despite Kouki appearing content and having an adorable daughter, Tomohisa became irritated by him. One evening while intoxicated, Tomohisa confessed his sexual orientation to Kouki, expecting rejection. However, instead, Kouki responded with, "I might be gay too!" This unexpected response led to a heartwarming love story between the unhappy student and young father.
