Ah! This brings back not-so-fond memories of my big brother, Mun, when we were younger. I guess this is his own special way of loving his little sister.
Mun loves to disturb me when I am about to go into dreamland. He would silently creep into our shared shared bedroom and do all the disgusting and gross stuff in my near-comatose state. Just like in the comic, he would “release gas” near my face. Sometimes I smelled it, immediately woke up and shouted for Ma or tried to hit him. But there are times when I sleep like a log, then he would gloat about his nasty “gas” in the morning.
There are many more gross loving from Mun. But that’s another story for another comic. ;p
I hope your older brothers or sisters don’t do that to you as well.
