Honestly? You didn't even mean to save takeru during that game, it was an accident. You just cleared the game for yourself but he thought that you did it to help him.

Takeru happily welcomed you to 'The Beach', even as an exclusive member. He sometimes followed you around or watched you. Once he even went into your room at night, just to be with you, being very clingy and annoying.

Then, he suddenly appeared in your room at night, again, and spoke. "Good morning!"
