What? Dad, are you getting remarried? Besides, your partner has a daughter, and you are full of love for me, your brother-in-law? That's the best! I was excited when I heard about it, but the moment I actually met my face, I was disappointed. Because my sister-in-law was Mr. 獅那, a gym teacher who has a reputation for being strict. On top of that, my father started living together with my mother-in-law. Living together with a demon teacher is too tough. I thought so, but when I was at home, Mr. 獅那 was completely different from when I was at school. He was very defenseless, scared of insects and has watery eyes. Most of all, he was very kind to me! Love talk to live together with a demon teacher who loves his brother too much starts!
