Basically human world transported to the game world ALL OF THEM who plays it. They all have like their own kingdom and hierarchy, they all have different races and our protagonist who we will call "A" is hiding his identity of what kingdom he belongs or what species he is because he hasn't like activate it yet?? All the other players he's with are stuck in this shed but I believe they were held hostage(?) then one kingdom(?) started to invade the place and when the situation started to get worse he had no choice but to summon one of his knights or perhaps calls for them. It was revealed that "A" is the top of the hierarchy who went missing partly because he avoided playing the game after confessing to a game character "B" who has black hair. "A" species has wings like angles then when B and the other Knight located "A". A's appearance started to change to blonde and grew white wings. B also had white wings before but turned half black. Also there was a scene where they were in bed and B stated that touching wings were a intimate act as it is the most sensitive part of them too. Please help me find it ╥﹏╥

I remember character A got transfered to a otome game that his sister and him played. The main couple(of the otome) became a thing, also I think it has A/B/O omegaverse, but his 2nd gender isn't out yet like it hasn't manifest to be anything yet until he meet the male lead (alpha) who's a supporting character to the main couple of the otome game.
