when the villian becomes male lead after transmigration [BL]

⚠Warnings⚠ :- english is not my first language so there could be some grammatical issues and this is my first story writing so it can also not turn out as your expectations. This story is BxB and also you can read it in the title and it may have some sexual but not so much moments so if you're homophobic I insist you to not read this or spread any type of hate
Thanks you,
