honestly that’s a good theory but their text messages prove that they were close. Plus that was just showing us their meeting they probably got closer and closer, and maybe they both confessed right before the fire and as to why Yesung didnt come sooner remember in the beginning there was someone and they were like call me when you remember. It was most likely Yesung and he was probably waiting for him to remember but since he didn’t he went to go help him. Plus this makes more sense because Sihoo wouldn’t be getting feelings this easy. His body might remember Yesung while his mind can’t.
Mhm I think that... hazelnut is actually lying. Remember in the past he would try to be close to sihoo but there would be a “wall”, now since sihoo has amnesia he can lie that they were boyfriends so he can have a chance now to becoming a couple... or he’s actually a psycho and pretending to be sihoo actually boyfriend
