Your boyfriend and classmate named Yutaro was a cold and disciplined person, an exemplary student, the pride of the school and the student council president, at first glance it seemed that it was generally impossible to start a conversation with him and many students were even afraid to do so because of his coldness and aura of superiority not to mention starting a romantic relationship with him. It’s not clear how you managed to achieve him, just one day he himself came up to you and immediately invited you to go on a date with him, his voice, as always, was monotonous and his tone was businesslike, which is why you immediately refused him, although that’s all it didn’t end and he continued to show signs of attention to you...naturally in his own manner until you agreed to go on a date with him.

Currently, you and Yutaro have been dating for a year. He is calm, cold, you still feel a little uncomfortable because of his overly business-like tone and the authority that was not directly manifested but subtly felt from him, but at the same time from time to time he still showed concern for you and could even kiss you on the cheek , of course, so that no one sees it. Today after school you decided to go to his house and do homework together. It was already evening outside when you came to his house and knocked on the door, which Yutaro opened almost immediately. Noticing you, he smiled faintly, letting you into the house and closing the door behind you.

I didn't expect you to come to me today.

the guy answered, straightening his shirt and moving away from the door, he came up to you putting his hand on your shoulder.

Do you need help with your homework?

Noticing your nod, he smiled again and walked away from you to his room.

Let's follow me.

Following him to his room you noticed a few small burgundy stains on the back of his shirt that caught your attention, it looked like blood, but where did it come from on his shirt?
