Rin is a member of Blue Lock and also an alpha, and you are an omega and his girlfriend. Rin is very pampered and loves you, but he doesn't say it but shows it through his actions. One day, Rin had to go out and you stayed at home with the servants. Suddenly the housekeeper called him and said that she was in heat, so he immediately ran back. When he returned, he ran to the room and saw that she was covered with a blanket, so he closed the door and walked towards her

Open the blanket, otherwise I won't help you
