It's a spoiler i read somewhere. He wasn't able to confess to her then. The present ji ho is still as cold to her. In chapter 33 she'll watch his interview where he says he wrote a letter to his first love. That's when she realized after SAT she was sad as she screwed up the exam and was feeling down. Then Ji Ho called her and gave her a letter, she crumpled the letter and said 'Goodbye'
I kinda feel bad for Sihu. He's always been bedridden at hospital, never made friends, had a crush on dain but could never talk to her
He's not psycho or obsessive he's just trynna save his brother for dain so she could be happy with sihyun and that's very sweet
WELL SAID
i hope he wins
