I liked the ending. Not that i liked that the man killed himself but it was more realistic. I was so mad when i thought he was going to forgive him and live with him as lovers because it made no sense. I felt bad for what minjae went through but killing that kid just because he was jealous, becoming a teacher just to be close to his dad, and ignoring bullied students made me hate him. He didn't deserve a happy ending.
Can we talk about how fucking irresponsible that teacher is?! She left a little boy unattended to fix her makeup and instead of being worried that one of her babies could get seriously hurt she was happy she got Jensen's number.
