How To Survive A Yandere Attack? (BL)

[NOTES: Due to the restriction of my story, I made a new and updated version.] When he opened his eyes, he suddenly transported as the older brother of the heroine in the r-18 reverse harem game, he severely hated. The problem was, he don't have any idea who the hell did he reincarnated with! He was not even in the game! And the worst part is, he needs to obtain the affections points of the six crazy capture targets in this shitty game! He was a man! A straight one! Luckily, there was a cute white cat system who was busy helping him... or it seems like turning him into gay? "Ding. New Mission Arrived. Spend a night with one of the capture targets." Mikael: "Are you crazy?! I don't want to do this anymore!" Cat System: "If the host don't do this, the host will immediately disappear and cannot return to the host's home." Mikael: "..." Fortunately, Mikael has a plan. He just needs to wait for the heroine to appear and help her earn the love of the capture targets, at the same time, he can also gather all their affection points! But there is one problem... An insane crown prince who can kill anyone he wants: "You dare deceive this prince?! I see, you are courting death!" The two-face manipulative wizard : "This potion will make you forget everything, then you will only remember me." The demon king who vowed to destroy the world: "Give yourself to me, or I will destroy the human race!" His abused guard who was secretly a hundred year old dragon: "I am the only one who can save you, and also the only one who can own you." The blackened elf king: "Nature is the power of us elves, be my queen and I will never let the human race suffer." The fifth cardigal who was the mastermind of all: "I can travel between space and time, and I can always... make you mine." A certain person: "..." Mikael: "Excuse me?! Who are you?!" A certain person: "Your husband." Mikael: "How to survive in these yandere attacks? ╥﹏╥ " -cover art belongs to the rightful owner.-
