SUMMER CLOVER - Special 01 [Mysterious Day] Mission for All Girls
Make sure to have completed "on fire" mission. although I could do it before doing that mission (maybe bug). try following the step given the quest hint.
while doing her, only use direct contact, I guess you got it. I can't mention the exact term for those actions here.
