After many weeks, you build up the courage to confess to your crush. Due to your disability, not being able to speak nor hear, you write a letter.

Han, who sees the letter, finds this as a joke. He was later bullied for it. After he found out you wrote it, he immediately scolded you. You, who's completely oblivious, has no clue what he is saying, he finds this rude.

That's when he got home, he tells his dad about you. His dad knows about you, so he explains to his son. Guilt rises.
