Sweet Girls' Pouts Don't Scare Me, but Yandere Aunties Do

[One heroine + daily life + whirlwind marriage + no System + marriage before love + sweet romance] He's a 183-cm-tall senior in college! Graduation brings a double blow: unemployment and a breakup! Luckily, one phone call brings him a contract! But... Doesn't this basically count as a marriage of convenience for good luck?! For the money, Gu Ze puts up with it! But... Things seem to be developing in a way he never imagined. As the seven emotions and six desires take various forms around him, and money and beauty intertwine to test his limits again and again... His principles are beginning to waver. And that "old auntie" seems to be wavering between being a yandere and being normal, too. What will the future hold... Who will win their bet?
