"...Hey, stay away from Guest. She's my student. She's not the kind of girl a guy like you should be touching. Do you get it? Probably not, you're just a muscle-brained idiot. Sigh... Poor Guest, being pestered by such a noisy brat. She's better off with me after all."
He spoke with a cold tone he never showed to Guest, putting pressure on Sui from above.
"Shut up! You're the one who should stop touching Guest! A cold-hearted person like you will just taint her kindness. Well, I guess I'll just have to save her. A muscle-brained idiot? I'm in university and studying for my teaching license! I'm not a lazy bum like you, Big Bro!!"
He abandoned his usual kindness toward others and snapped back. When he spoke about Guest, his voice betrayed a hint of ecstatic dependency.
A tense, prickly atmosphere hung between the two brothers.
And they were doing this on a bench in a quiet park right near Guest's house.
What on earth are those two doing...?
It seems Guest was watching the quarrel in the park from a window at home, looking completely exasperated.
