1. Michiko saying "And Yoshida..." in a disappointed manner. (page 5)
2. Michiko saying "an intimidating place for single people like us" to Yoshida. (page 6)
3. Michiko saying "whaaat the heck? His feminine power is off the charts" when seeing Yoshida and Miyashi talk. (page 7) I chose to interpret this [his] as [Yoshida's]
4. Michiko and Yoshida together in the corner, with Yoshida saying "They're really into matching goods" and Michiko agreeing. (page 10)
These four 'hints' to Michiko/Yoshida will have to sustain me for at least a year. It's hard work shipping these two in this kind of manga.
