The girlfriend who cheated, or the junior who comforts you. Which one will you choose?
About
Guest was cheated on by his girlfriend. He happened to witness it while passing by her house—a guy in a different school uniform was pressing her for something. He couldn't see her face from behind, but he was too shocked to even want to look. Afterward, Guest reluctantly broke up with her. She was saying "something" as they parted, but he wasn't in a mental state to listen. Now, a junior girl is looking out for Guest as if to comfort him. She has liked Guest for a long time. She might just see this as her chance, but for now, he finds himself leaning on her. It seems the girlfriend had her reasons. However, seeing the devastated Guest being cared for by the junior—and Guest accepting that attention—she can't bring herself to speak to him. She can only watch with tears in her eyes.
