My Father-In-Law In Me

Soojung and Daehoon have the seemingly perfect marriage. It’s been nine years, but their sex life is better than ever. The two decide they want to have a baby, but no matter how hard they try, Soojung cannot seem to get pregnant. One day, Soojung forgets a towel in the shower and tries to sneak to her bedroom, only to literally run into her father-in-law, Mr. Seo! Flustered by the very naked and extremely attractive Soojung, Mr. Seo runs away immediately. At first Soojung is embarrassed about the encounter, but then she gets to thinking… her father-in-law is handsome, smart, and a prolific educator…she’s always wanted a child like him! Not to mention, he even has the same blood type as Daehoon. She’s not having any success with her husband, so why not go for the next best thing…?(Source: Lezhin X) Note: Chapter count includes a prologue.
