I agrre with you! It was obvious that he was not sleeping! He was blushing and even open his mouth in the second frame. And he was pretty calm when they were talking about the jizz in his face. I do not understand how people were confused about that! ╮(￣▽￣)╭
The blush at his face was from the time when he was drunk the blush was even there when he was peeing .i think the blush was more like his face was read because he was drunk .i dont know if he was awake or not but the blush i think was there due to him getting drunk not embarrsing blush.and i am not being rude here please dont think like thay .it was just my opinion.:).and the mouth opeing was more like either due to because of that long hair guys hands or because he was sleeping like that .becauee his expression was dead not even aroused.
Ah well.i read it again and i got confused about the open mouth. ╮(￣▽￣)╭ sorry you all.
Everyone is entitled with their opinion! I just did not understand yours, but I still believe he was aroused.(〜￣△￣)〜
I really don't think Masahiro was asleep when Tsubaki-san jizzed on his face, everyone! He's blushing hard in the flashback... he's just got his eyes closed because, you know, jizz in the eyes is not recommended (⌒▽⌒)
