Read Let's Do It After We Marry Manga:
Moa never thought much of her cold, stern boss, Gunhoo. At least, not until that fateful incident at the company workshop. Ever since accidentally seeing him in the buff, Moa can’t get him off her mind. After weeks of fantasizing, she finally asks if he’d like to spend the night with her. That’s when he drops a bomb: he’s a virgin, and he’ll only sleep with her if she more.. marries him. The problem is, Moa doesn’t believe in marriage! With such different values, will these two make it down the aisle?
