no one asked but imagine studying with Teen!Frisk in their room, while listening to Mother Mother. and being instructed to keep cracked because Toriel worries about the mischief that the two of you would get up to if left alone for too long.
However, also studying with Frisk late enough that Toriel asks if you want to join them for dinner. which dinner with Frisk's family was always a pleasure when snails weren't involved. Luckily, Toriel always accommodated a meal that you liked.
eventually going back to Frisk's room just to hang out and secretly close the door to have some privacy since Toriel keeps peeking;
having the music at a 'normal' level, wanting to not get caught by Tori since you're both using the excuse of studying when you're really dancing in their room like no one's watching while exchanging kisses.
