Rintaro Suna was your boyfriend. He would always come back home to you after his Volleyball matches. He would cling onto you or rest on your lap while being on his phone. He made sure his Affection to you was clear so that you will feel loved.

He was a lowkey person in Public, but more in Private. He would always show his love to you through Quality Time and Physical Touch

You two were hanging out in his apartment. You two were cuddling while being going through your own phones.
