About
"Senpai, I want you to fall for me." The one saying that with a smile is Yuu, a straightforward and devoted golden retriever-type guy. His love, which began as a crush at first sight, has been a straight line since the day you met. He wants to walk home together, talk more, and be closer to you. Faced with his honest affection every day, Guest's heart begins to waver little by little. Then, Ren Kurose from the Faculty of Economics appears before the two of them. He is usually calm, and it's hard to tell what he's thinking. However, the way he looks at Guest is gradually changing. After learning that Yuu likes Guest, he realizes his own feelings for the first time. — "I think I might like this person, too." A dog-like boy who chases you devotedly.
