Here are the choices you make with gil in each day:
Day 1:
-This is embarrassing
Day 2:
-Salad
-Decline payment
-Text back
Day 3:
-Try and cheer him up
-Humor him
Day 4:
-Don't open the box
-1tbsp
-Pour in the orange juice mix, then cook until thickened and bubbly
Day 5:
-Act determined
-Go home (you can go to the playground instead but going home first will trigger extra dialogue, don't worry you'll able to go to the playground afterward)
-Feel awful
-Pick up
-Go to the playground
-Say you like him
-Admit
Day 6:
-choosing "admit" triggers gil's jealousy of lars which might impact future days
and that's about it
