He did took her ultrasound at his home, remember when he pick up something in her trash where they were hs Mincheol and her picture. Also it was stated in another chapter that he wanted to use it as his card , but end up not doing because he don't want to pull that kind of love without her consent. Maybe his plan was to made her enters on her family with a fake pregnancy idk
It’s the ultrasound that Taeha took from Haesoo’ house in this panel chapter 41 https://www.mangago.me/read-manga/tears_on_a_withered_flower/uu/br_chapter-318911/pg-33/
Haesoo explained she had a miscarriage and the doctors told her body was too weak to have babies. We know somehow she’ll have one with Taeha #mytheory

No one is talking about the baby ultrasound pic on Taeha’s coffee table or the fact she was crying because she’s pregnant? What the hell kind of progression is this (╯°Д °)╯╧╧
