I wasn't really confused until the last 2 episodes and it sort of cleared up, but I'm not sure why Do Hoe faked…
regarding the gang thing, I saw it as either as self-hatred (not accepting your own attraction to someone) and using your friends to hide it/let everyone know you are def not gay, or, his feelings were not reprocitated and he took revenge (tho his heart wasn't fully into it as he himself couldn't physically hurt the person he liked) just my take on this
