Kataomoi To Parade
The first story is about a guy who has been in love with his childhood friend for years but never confesses. He always wishes that he would be a girl because his childhiid friend would always say that he was his princess and himself the hero. I kinda started shipping Touma with senpai though. Second story is very incomplete and is about the senpai and a research associate.
