He was scared that eunho will deal with the same bullshit he has dealt with considering being gay , especially from his family
He was scared because he knows he isn't courage enough to fully accept his feelings or face the world , he isn't courage enough to be happy
He was scared and sad that those feelings might harm eunho and he wouldnt be able to ease the pain
He didn't want eunho to become like him , it is not fair but it is understandable if someone goes through shit for being gay , they wouldnt want anyone going through the same shit
He was sad and scared that eunho still has feelings for him and it wasn't mere childish act
Why did Jaeha look so sad when Eunho told him about his feelings?
