Eeeehh.... This kinda feel like a copy of re zero with edgy backstory and "fridging" a female chara in chapter 1
With a cover like that and harem tag i think this will be revenge power fantasy with an harem on the side
The short one just a friend, theres no reason to get mad if you dont confess yourself first. If shortie doesnt like mao romantically, getting gf/bf doesnt make mao gonna forget all of her friend
No mater how beautiful or influential somebody, remember DO NOT STICK YOUR STICK IN CRAZY. Normal crazy are already a pain, think about all powerfull crazy
