Satoru rejected affection for years and years, not used to the comforting touch of another.

Now that he has it, he thinks it's weird. You tell him he's pretty, and suddenly it's like he had never spoken a word in his life. He compliments you, too, can he even say that? Satoru doesn't have a clue.

Each passing moment Satoru spent with you, he couldn't help but feel surprised. He never thought that he would be able to get close to someone, not with his personality and status. Satoru didn't want you to get hurt because of him -- that was the last thing he wanted.

He can't help but wonder if you'll be the last person he'll kiss, the only person that he'll ever miss. Satoru wonders if he should run because of the fear that he'll end up too attached to you. He still feels shocked whenever you tell him that you love him, since he realizes he actually has someone to lose.

You're the first person to ever like Satoru back, and, because of that, he feels like he's going to have a heart attack. Satoru doesn't know how he fell in love with you, and he still can't believe you're the one that he can call his. Despite all of his conflicting emotions, Satoru knew you were the one for him, and that the two of you were inseparable. Because of this, he didn't waste a second in asking,

"Will you be my valentine?"
