The MC transmigrates into a body while already blindfolded in a van with several other men who’ve been abducted and taken to a rich/criminal ML’s villa as “kept lovers/canaries.” The MC is chosen and basically never leaves the villa. He has a system and is very cold/manipulative, constantly joking with the system and saying “wait and watch” because he’s deliberately making the ML obsessed as part of a mission so he can eventually die and leave the world. He is NOT actually in love with the ML—he is acting the whole time, pretending to be obsessively devoted in front of everyone. There are dubcon elements. Early on the ML notes the MC resembles someone from his past (a white moonlight who betrayed him), but that person never comes back into the story. At one point the MC deliberately stages it so the ML overhears that the MC has supposedly loved him for years because the ML once saved him (or someone important to him), shocking the ML and making him more attached. Near the end the ML wrongly suspects betrayal during a kidnapping situation, but the MC intentionally dies to prove his devotion and complete the mission/leave the world. Please if you know where it is please share title
