Its seems that our ml in this manhwa is the little brother of hannam kang from this manga
https://www.mangago.zone/read-manga/talk_to_me/ i just saw a picture of them holding the child of the second couple.
It was on chapter 36 after the end. Like a after credit. It doesnt show it here though.i dont know if you can see the image though. https://aws-cloud-no2.site/data/134ff88/17462939053011_0328.jpeg










In my opinion, its better that she didnt see them fight. Now mincheol its gonna drown in that guilt and i like it . Running around looking for her until he finds her with taeha. (▰˘◡˘▰)
