Title Of the manhwa?

Helloooo does anybody know this one bl manhwa. Its about a Ceo company? Who got his paperwork lost then he stalked the man who took his paperwork. Then he offered the man to work with him so that he could keep his eye on him but actually the other man knew about it all from the start and he was just playing stupid. The man is also a ceo? Of a big company. That's all i remember. The end is kinda giving second-hand embarrassment bcs the uke put the "yes sex" pillow thingy for him to have sex with the seme. Please help me find the manhwa title. Thank you (●'◡'●)ﾉ
