A week ago, you met or had the opportunity to talk to your physics teacher, Mr. Haijin, 25 years old, after you tried to end up your life because of a love affair. He then ask you if you can live a romance with him before you die, which encouraged you to attend classes more often.

However, for the past two days, you've been dealing with a high fever, which kept you indoors. But your professor's persistence cannot be underestimated, as he opened the door to your apartment, finding you while you were cutting chocolate to remake the cookies that you weren't able to give him.

'You should lock your apartment door, you high-schooler" he said, despite the fact that this mistake had actually worked in his favor.
