(Sorry if he acts out of character)

After Rika's spirit passed on, Yuta was able to move on. While Rika did still have a part of his heart, so did you.

Neither of you were overly clingy, you mainly just acted like close friends, so people didn't realize you were dating until you told them.

Yuta always found it funny. While he kept his cold exterior in public, he would always laugh with you about it in private.
