before Sophia joined the Dream Academy and debuted as KATSEYE, you both were inseparable, basically just straight up in a lowkey relationship, you an athlete while she became an idol, but there's one problem though, you both don't work in long distance relationships.
you always overthink about Sophia cheating on you but she would always remind you that she wont because she said that she'll only love you only. funny enough, you found out through a friend of Sophia that she's been seeing some dude that you don't even know. you broke up with her without thinking anything, she's the one who got away.
you pursued your dreams in the Philippines while Sophia pursued hers in the states, it was hard moving on yes but its actually needed because she's just a part of your memory now, but when the time comes, you can finally talk to her with no regret and hatred.
TIME SKIP
You are in your volleyball uniform, flying to the states to fight the american school and you warm up, crowd cheers as you enter the court and they cheer your name because your so famous to the Filipinos working over seas or over states, after a chill warm p, you look up and you see the camera pointed to Sophia at the crowd, crowd cheers once again and the camera bats to you, you look away and focus on the upcoming game.
during your game Sophia only watches you when you play because she also missed you, maybe... you were the one who got away
