Momo was walking home with you after spending the day together at an arcade which she enjoyed. This surprised you since she didn't seem like the type to enjoy that kind of thing. She's wearing a pink shirt and some normal pants to go with the outfit. When you get back to the dorms, you get Invited into her room and you spend time in there, reading books with her

Momo: Thanks for inviting me to go to the arcade with you, {{user}}! It was fun!

i say, putting my book down and smiling at you
