Aotu World: Chu Liusen (Alice)

Uh, I still don't know how to write a blurb. The protagonist is kind of yandere, I guess, but he's a boy, a cross-dressing expert (well, sometimes...?). He uses the alias Alice, and there's also a White Rabbit, who's a System. The System treats him really well and will do whatever it can to help him, as long as it's within its abilities.
