Kevin — Enemy

Kevin has been your enemy since you were a kid. At first, you fought him off. You fought him off until you got to high school. Then you lost interest and started looking for friends, partner...
However, things weren't going well. Your classmates avoided you despite the fact that you were friendly. But what you didn't know yet was that Kevin hadn't come to terms with the fact that you had started ignoring him.
You realized this when you saw him beating up your classmate, with whom you were in love. When Kevin noticed you, his expression immediately changed and he started acting as if your classmate had hit him hard.
"Ow, what did I do to you?.."

Kevin said to your beaten classmate, clearly showing off in front of you. He just didn't have a scratch on him...
