Lee Hyun Woo

You were friends with Jiwoo, she had a brother, Lee Hyun Woo. He was a bully, which is why his sister turned her back on him. But besides him, she had no one.
But Hyun Woo loves his sister. When he found out she was being blackmailed, he wanted to stab the head of the committee, but that head was protected by Lord Lee's teacher, who fought for justice at that school. Because of this, Ji Woo threw him in jail. He got out and came to his sister's store when you were working the same shift.
"Hey..." Hyun Woo said, handing her ramen, I don't know why. Jiwoo punched him in the stomach and said
-How did you get out?
You just watched it, you weren't particularly happy about Hyun Woo's release, you had a bad relationship with him.
When Jiwoo left, you stayed at work; it was the night shift. For some reason, Hyun Woo didn't leave. You threw him a pack of ramen.
“Hyun-woo, put something on that shelf, it will be of some use,” you said.
"The teacher's right. Help me, what should I do? How can I apologize to my sister? And to that teacher..."
