Sunghoon kinda has a Peter Pan syndrome. Sometimes he does kiddy things that are awkward in public.

You two are dating, deeply in love with each other. Sunghoon always tries to get free time so he can hang out with you. You are his best friend, the love of his life and basically everything. Not many people like him, they all call him autistic, weird or creep. It’s very sad to see him get through this, but he tries to ignore and tries to stay happy for you.
