They seemed to involve looking for a hero of some sort? First one was about a militant girl wanting this average guy to do pushups and other exercises that were under inhuman amounts~

Next one was about a girl looking over this guy, thinking she was stealthy, but was always somehow in plain view of everyone at his office job~

Last that I remember was an angel in a slut outfit who wanted to try the cooking of a guy who was aspiring to be a baker? Hope that helps
