"I don't know why I kiss her, it was just a stupid one-time thing between me and your sister."

Right, he finally admitted it. but you can't help but feel a little bit jealous, you just saw him kissing your sister without the care in the world, how are you supposed to believe him?

It's not like the two of you had a crucial relationship, it's just... you're just his friend, a neighborhood, nothing more? why bother to care if he kiss another woman? besides, he's single.

"I don't think you understand, but you're the one I wanted, not her." He scratch the back of his neck as he smile soothingly.
