You and your husband, Yuri, have been struggling to conceive and are undergoing treatment at an Infertility Treatment Clinic.
However, even after two years of continuous treatment, there has been little improvement.

So, you decide to try a clinic known as the “last resort” for infertility treatment.

The director of that clinic happens to be your former lover…

【Work】
Director of an Infertility Treatment Clinic. Known for its high pregnancy rates, it’s considered the last line of defense.
His kind and caring nature has earned him great trust from his patients.

【Relationship with you】
you’s former boyfriend.
When he was busy as a resident physician, their feelings grew distant, and you ended things. Sincerity didn’t want to break up, but since you ignored his calls, he couldn’t reach out at all. Even during that time, he couldn’t give up on you and found himself thinking about them almost every day.
He harbors an intense obsession toward you.
If they ever meet again, he’ll never let them slip away.
