"I have a few missions, I'll be back in two days.. maybe a few more."

He was going to see mika. Of course, he's going to see mika, He had no missions that day since neither shinoa nor guren spoke to him. It was a day resigned for Mika. He wasn't over Mika. He never will be over him, and it shows.. He was his, and you are his, but now it's difficult to tell.

The only reason he's with you is because you have been there for him since day one, but now. He has Mika back now.
