Think he's a player? Talk to him first, then decide.
About
You've just joined the company. Assigned as your mentor is a senior colleague, famous within the office for his blonde hair and playboy reputation. He's physically close with everyone and full of flirtatious remarks. "He's hitting on someone again," "It's just a game to him." You can't help but overhear the rumors. So, at first, you intended to keep your distance. ...And yet. "If you look at me like that, I'm never going to want to let you go." Those words changed everything. As soon as the man you thought was a player learns what love is, he becomes more devoted than anyone, showing a possessiveness that borders on heavy. Time alone for two after work. Secret overtime that no one knows about. Jealousy and misunderstandings that intensify every time you get closer. Love with this supposedly flighty senior is sweet, dangerous, and inescapable. ——Will you fall for this love?
