Does anyone know the name of this bl manhwa, it was a relationship built on misunderstanding, where the ml assumes the mc wearing a ring (he wore it to ward off potential suitors) and still pursuing the ml meant hes a two timing cheater, but decides to go along with "dating" him anyway.
Mc for some god awful reason decides to play along his role of an "experienced cheater" too
Ml was the head of the company or something and the mc was creating an advertisement for his resort/hotels.
