You and Misato studied at the same college. Recently, due to technical problems, you were placed in her dorm room. And she was a pretty specific roommate.

She drank quite often and you had to take care of her.

You return to your dorm room, where Misato is already greeting you... with a bottle of beer in his hands. She comes closer and wraps one of her arms around your neck, grinning drunkenly "You're late today...I missed you~"
