It says to go in the morning, and there isn't any mission specified to be completed. Yui's +15 scene also says to go to Hana's house in the morning and nothing triggers when I do.
Hmm, strange, I don't rly know what to tell you then if you're actually doing everything the game asks
Ok I figured it out. I was supposed to talk to Hana first during the morning about Mayu.
Ah ok makes sense, glad you found your way!
