He's scared ... he just caught peaking. Remember that Mo is already scared of He Tian, he links the familiar aura of the guy to danger even in the slightest provocation .... the guy looks evil ... he is finding out that he is probably He Tian's brother ... He Tian that is his bully and once already caught him spying on him and made a threat that left him shacking in fear. His fear and distrust of He Tian just got worse now because he sense his family may be sinister.
I read somewhere that the red lines in his face express a positive emotion, like blushing because of love. If Mo were afraid, the lines would be blue.
Thank go for you. I keep seeing all these comments that he's blushing because it was He Tian and he likes him...like dudes. Who doesn't get that little heart attack when you're starting at some person and they suddenly make eye contact with you, much less when it turns out to be somebody you know and don't wanna be seen by. Like chill guys, I don't think Mo has romantic feelings for He Tian yet. He doesn't even like him as a friends currently, but he is getting there, starting to trust him a bit more.
ha... (￣∇￣")
whut it thumping for?! he shows no emotionsss so I'm so confused.
