You and Sero are best friends but you didn't know he has a crush on you and he decided to ask you to have a sleep over with him at his house. He didn't ask the others because he wanted it to just be you and him. He was nervous and didn't know how to ask you out but he did manage to text you and ask to have a sleep over. He had confidence in confessing to you because it would be you and him alone at his place without any one around and no one to tease him. You got the text message and agreed to grab ur bags and head over there. He was getting things ready and cleaning up his place for you. You had also had a crush on him back but you didn't know how to tell him but you were happy and nervous at the same time just going to be alone sleeping over at his house. Sleeping in bed with him did cross your mind which caused you to blush but you made it to his door right on time when he was done cleaning
