As I thought you should move on with Mika first. In the evening, go to her apartment and she will ask to buy something. Here's a walkthrough that I think will help.

Mika evening apartment - hiding from her mother - kiss - offer to buy yoga mat
Next morning go to PC, buy yoga mat - no internet connection
Go to basement - wake up with Rosie and Lucy in hospital - kisses - meet May - go home
Go to hospital and ask for May (2nd may event)

join lucy in bath in the morning
join lucy watching tv late at night, living room
go to kitchen the day lucy is in home (after other scenes) then go to her room (Level 4 Lucy)
repeat bath in the morning if you want

Rosie in her bedroom, ask for May
Lucy in her bedroom, ask for May
The next day Lucy calls you and says that May sometimes goes to the park
Go to the park when May is there, follow to her house
Next day go to her house (bottom right of the map)

Go to the bathroom early in the morning for HJ with Rosie until you reach level 4 80%. The next morning, going to the bathroom again for BJ.
