Thank you for liking my game! For the endings, ending 4 is the best you're going to get with Leander in terms of romance. The best ending for the MC is supposed to be the true ending.
I'm pretty sure there are 7 endings in total, I remember I was planning on making an ending guide shortly after the game released, but I never got around to it. Sorry about that!
As for ending 7 I remember I had a reason to why he acted out of character, but I don't remember the whole reason. I'm pretty sure it was because Leander fell out of love with the MC because they didn't do everything that he wanted them to. In his eyes they weren't the perfect lover. That was the main reason as to why he fell in love with Alice in the first place.
I was planning on expanding on this story a bit more in the future. Maybe creating a prequel to the game that showed Leander's life when he used to work at the circus?
Thank you again for liking my game and I plan to keep working hard on my other games as well ❤️
