This was a really sweet story ️ The ML bullied the MC in high school (only once) because of fear about his friend hating him due to his sexual orientation and him loving his friend. This led to the others in class bullying him due to the ML being a popular guy in the class and they followed in his footsteps. The ML has always felt apologetic towards MC so applied to the same college as him and their love blossoms since MC has always felt the same way as the ML. The MC had never blamed the ML (his only friend) for bullying him and ignoring him because he was insecure too and thought that the ML noticed his feelings
