and why is this heart-breaking and almost heart-breaking?
A year late, but I'm guessing it's Ise overhearing Hyuuga commenting on conveying "affection and gratitude", and Ise feeling guilty about her own impure reasons for... dousing her face in chocolate. Kind of a stretch though.
The wicked thoughts, that is!So, what are you planning on giving me this year, Ise?Only fools would neglect such romantic customs...What's wrong?Wait, I only wanted to rinse it off!Taking a bath at noon is a good habit to have.A day to convey your affection and gratitude to your beloved person in the form of a gift, huh...?
