His father has already passed. The guy in the video call is the dad's best friend who had a crush on her and was her doctor. The MC helped them get together
Also the mother had cancer but taeseok gave her a potion that healed her
Thank you Bro, i just recall this part now
Potion?
He got a potion from the system to heal his back, but he was gonna use in his mother instead(she was is her last days) so the system found a loophole that I don't remember and both of them got healed. After all (we all predict but not 100% sure) that the system is his father
Oh my Gosh! Why do i not remember that important part of the story. Maybe i skiped a chapter. Thank you so much.
Wait, his mother and father still alive? The one in video call (I already forgatten some parts of the story) help me clarify/summary the plot
