I definitely understand being too lazy to learn (since tbh I'm pretty lazy myself lol). I still encourage you to do it if you can though, it's honestly pretty fun making one and seeing your idea actually come to live! ^^
The next VN won't be yandere-themed (at least it won't focus on that aspect as much as Sweetest Valentine does). Instead it'll be more focused on mystery and slice of life-ish aspect.
Thanks for the support! :D
