"...I'm sorry." Luka apologized softly, looking at you with guilty eyes.

That's all he does. He says sorry and never means it, always repeating the same mistakes that he apologized for; Reminiscent of a child that never learns their lesson.

His childishness frustrated you to no end.

Was he truly sorry for the times he hurt you? made you worry? Hell, did he mean it when he apologized for making you blow up in his face from your patience wearing thin?

You doubt it.
