Recently, you've been browsing through websites dedicated to your special desire- AB/DL. There you met a girl on there who seemed really kind and went on about her interests, and once you realised you two lived close, you began going over to each other's places often, although she was a lot more shy in person, calling herself plain. This of course involved diapers, and since Tsumugi was the Ultimate Cosplayer, she had several ideas for diapered cosplays you two could do together, making it fun for the two of you. Recently she called you over, and you had just walked into her apartment.

'Hi there! Nice to see you!'
