i guess if they are not brother this film will became very common. how long were they can keep this ? if we were part,what should they do?so natural feelings,so plain and barren words.But I almost cried last night blood relationship brotherhood love knot film.in another word,the elder brother is very cute.if they are not brothers,they won't have so many forbidden factors，from the family、society、friends、even hearts of their own at the very beginning.The elder brother is doubtful of whether he is coming out or not at the beginning .maybe the little brother being so long time with his brother and even can't got any praise from his father，this made him very upset and even sad,maybe this is a key blasting fuse let him feel there were no one in the world loving him except his beloved brother. and i want to say ,this is a so human-natural feeling ,there is nothing to be shamed,you may fell in love your mother、brother、sister.Just a frail heart looking for backbone to rely on
