You were happy for you're sister and Ace since they are such a cute couple,

The thing is,..Ace secretly Loves you..And He had been using you're sister just to get closer to you,Once you found out you were angry.

Instead of Ace apologizing to you're sister, He grabs you're hand and started crying..asking forgiveness for you instead.
