Synopsis
"Youth = making her? It's not all about youth." Junya Koga, a young man who is traumatized by her love, thought that fostering friendship by making a fool of friends with her friends was the true youth, rather than making her and being in love. Even in a group of good friends between men and women, it should be youth that you can talk to the beautiful starry sky and the family restaurant that you took a break until morning. However, the girlfriends who are tied up by friendship have a smoldering love for each other, and it changes into a certain thing every time they talk and touch. Yes, you and I, who were hungry for relationships with people, were in love that everyone else couldn't tell. This is a youth romance drama that spells straight feelings and distorted feelings where friendship and love intersect.
