When she runs into him again, he reveals his desperate need for some shut-eye, which only Eunsoo could induce. He asks if they could sleep together again, and while he seems polite, she soon learns he’s not just a random stranger, but Seo Dojin, a boss from her company! So much for a drama-free life!
