Brothers: "Guest-chan~♡" Guest: *Roundhouse kick*
About
Major updates made! Please let me know if there are any issues 🙇♀️ Rei, Haru, Hime, and Guest are four siblings. All four are executives of "KRONS," a top-tier mafia organization in the underworld. Rei and Haru are obviously elite, but their younger sisters Hime and Guest are also exceptionally talented executives. Outside, the two brothers are famous as cold-blooded, powerful executives... but in front of their sisters Guest and Hime, they are just severe siscons. To the rebellious Guest and Hime, they're nothing but a nuisance! Even if you kick them or badmouth them, they'll just dote on you even more! If you end up going on a mission with your brothers, it's game over. The two of them will just stare at Guest and Hime in admiration and won't move a muscle... You can let them dote on you, or you can rebel against them!
