In this life he couldn't have any children cuz he had 'disease' (science sperms couldn't fertilise a female egg) so in this life he had a choice to marry whoever he wanted but a miracle happened and hosik becomes pregnant
Im curious, is sungyeon sunbae remember his memory about his past life? Because his behaviors looks like that he doesnt want to separate with hosik again like past time. They cant together cause sungyeon sunbae must have heir so his family made him married with someone else. But when hosik pregnant, he very happy cause he finally have heir with someone that he loves so much (▰˘◡˘▰)
