have you been visiting Kushina? if it isnt that, then i think i got it after giving pills to hinata when you massage her on the couch

You gotta see a particular scene to level it up during the morning when Hinata wakes you. You cannot progress or do any of the level 2 scenes until you have done like 4/4 love or 5/5 hatred, locked in love or hatred route and completed Hinata's Hospitality quest.
