This cg is Haato wearing a maid outfit. To get the cg you need to
No. 1. go to the maid cafe while on a date with Toru once before No. 2
No. 2. accept 'mister princess' the cross dressing audition while Toru's in the agency at the same time (mine was 12th March)
If done right, Haato and Toru will audition for the same role and make a bet. Loser wears the maid costume. You have to win the audition.
No. 3. Not sure if you need to get the maid costume (M size for Haato) or not though
After that it should show up eventually during one of the night dates. (doesn't matter if Toru is sub or dom, top or bottom)
