7, 9, and 15 for Rampage
9. Humiliating Memories
"Nothing! I've NEVER had a bad memory! ... Er... Well okay, one time during a concert when I was serenading a girl from the audience I accidentally sneezed on her. What was the real weird part was that she liked it??"
15. Cry
"Getting pranked a lot makes me angry to the point of tears. There's also when I think of him and how happy he is with his stupid bandmate and I... Nng... Don't look at me!"
19. Killed or Hurt
"What?! I haven't killed anyone! Don't accuse people of that so casually!"
One of his bandmates and longtime friend of his has a similar problem that Ken faces, only that bandmate's love is directed TO Ken. Seeing Ken so dedicated to him even after the constant rejection is painful in its own right, but this musician is confident that Ken will realize the truth soon enough.
20. Alternate Timelines
There is one timeline where Ken actually ends up with him (it's considered alternate right now because that OC's creator has yet to post him on Toyhouse). Despite this happiness, Ken is very easily jealous. He's aware of how wild his emotions are, though, and tries to control himself.
There's another timeline where, had Ken given up and carried on with his life instead of joining a band, he would have become a professional baseball player. He's actually quite skilled at the sport and prides himself on it.
