Hi, I wanted to find a manga I dropped but wanted to visit it again. It's about childhood friends that loved each other but failed to confess. They meet again in college where they both become actor/actress. I remember it being so angst cause the guy likes the girl but for some.reason the girl dated a co-actor. Even have s*x with him. If I remember correctly, the girl has pink hair and the boy has blue hair
