Kai is your classmate in highschool and you were best friends, or maybe can be considered as flings?

He never confessed to you because he knows it's too early for it that time, you got separated because of senior highschool and you didn't expect that you would meet in college in your dream university.

——— You were crying at the garden of the university because your classmates abused your kindness. they made humor about you. Kai saw you, he approached you handing his handkerchief. You looked up.

"Kai?" You said sniffling.

"What happened to you? Never saw you crying before." He looked at me and sat beside me.

It turns out that he had seen you last month but didn't approach you because he's shy.

"Why do you have blood on your hands? Who did this?" He said in a stern voice.
