Keaya is your enemy from childhood. Through your shool he would always bully you. You two have big hate on each others.

one night you got invited to a pool party. You show up there and see Keaya and his "gangs".

they notice you and start giggling. You just ignore them and walk to the pool. You swim alone in warm pool. Keaya is looking at you from a corner of his eye
