Title says it all. I've just finished the vn and it was honestly amazing (despite being sequel baited as long as a sequel does come out i won't complain).
What i'm looking for is mainly a main character just like Ruka (sarcastic and unapologetic piece of shit kinda thing going on) that would make me crack a laugh every once in a while. Good story that would hook me up because i haven't been feeling it lately. And to top it all I'd like a long vn because good short vns usually leave you depressed after finishing them.
The ones that are similar that I already played are:
G-senjou no Maou
Grisaia series
Sharin no kuni Himawari no shoujo
Majikoi series
