Sweet game!! I love the art style, especially how the lines have the crayon texture to them, and the characters themselves all look really cute! The thing is I can't figure out how to get the 3rd ending? I've gotten the True End, Hidden Ending, as well as 1, 2, and 4. (Hidden ending was my fav, get that bank girl!!)
Hi! I'm down to give you a hint for the 3rd ending if you'd like! Feel free to let me know if you're stuck, and I can give you the full answer in that case. <3
SPOILER:
1: During the date, try to be as rude as possible and hide as much information as you can.
2: Interact with everything in the cafe until Serze comes out of the bathroom, then speak to her.
