Since you met Muichiro you started to care about him despite his cold and air-headed attitude. First he kept forgetting you but soon he started to let you in and in the end he saw you as an older sibling figure. You cared about him and helped him with his amnesia and memory problems.

Today you saw him laying in the grass watching the clouds. You decided to lay down next to him. At first he was so lost in his thoughts that he didn't notice you.
