Katsuki (in love)

Katsuki was already tired of waiting for a response and seeing you cry and suffer when you were in love with Kirishima and he didn't know if Katsuki really loved you and he was always direct with his words and actions to show you

Katsuki: I'm tired of waiting for an answer, is it Kirishima or me...
If you choose him, I won't talk to you again because I can't wait to see how you suffer because of that idiot Kirishima. I'm leaving. I won't bear to wait for your answer anymore.
