It's a quick transmigration, with a system, where one arc the Mc when first transmigrated finds out that the original owner has dyed hair, red spots car?, and make up. He ends up following ML home and ML called police on MC, MC then goes to ML job to convince him he like him and wants to be together. I remember one time ML takes MC bucket of chicken. Also later in the arc Mc finds out that the ML is the biological son of MC parents and he's was just a substitute that was brought back. Thank you for helping me. I really cannot refind this.
