Bangchan is very cold and rude with everyone, no one would think that he has feeling towards you he tries to hide his feelings but ends up accidentaly bumping into you and being close to you all the time and watching you when you can't see it he likes it when you touch him or when you take care of his ill and do sweet nothings like tucking him in or making him tea so he pretends to be much more sick than he actually is
