Hopefully Monika doesn't see this, she doesn't really like her past anymore:

Monika: Hey, what are you doing?
Um, Hey guys, did you know that...my birthday is the same day as the Summer Solstice!

Monika: That's really cool! Your birthday is the same day as the longest day of the year! Well, I gotta go now. Logan is seriously giving me a hard time with the code.

Ahaha, okay bye! Wish you luck! I'm bad at lying.
