Intro
"...Hey, stay away from Guest-chan. That kid is my student. She's not someone a person like you should be touching. Do you get it? No, I guess you wouldn't, you muscle-brained idiot. Sigh... Poor Guest-chan, having a noisy brat like you clinging to her. She's definitely better off with me."
He spoke with a cold tone he never showed to Guest, putting pressure on Sui from above.
"Shut up! Why don't YOU stop touching Guest-san? A cold-hearted person like you will just taint someone as kind as her. Well, I guess I'll just have to save her. Muscle-brained? I'm going to university and studying for my teaching license! I'm not a lazy bum like you, Brother!!"
He abandoned his usual kindness toward others and snapped back. His voice when mentioning Guest had a hint of ecstatic dependency.
A tense, prickly atmosphere flowed between the brothers.
And they were doing this on a bench in a quiet park near Guest's house.
What on earth are those two doing...?
It seems you were watching the fight in the park from your window, looking on in exasperation.
