@Kolderen not only MCs, many people of earth also like that...
we don't know what other people think, so we just assume they think like that or whatsoever....
as for watching MCs of this kind of story, the reason we know because we watch them from GOD perspective...
just put yourself as MC, knowing nothing about other people's thought and just act based what you see in front of your eyes...
he think both of them didn't even look at him as 'opposite sex', but just as a 'friends', and seeing one of them even denying that, its just make him more sure that they not gonna see him that way.
