So the scene where they’re all sitting down and eating and take off their glasses at the same time is something that happened when it was just their family, it was a one panel joke to show to the audience that hotness runs in the family (I couldn’t find which chapter but it’s one of the earlier ones) but there is a scene where taemoon sees his mom and dad take off their glasses and realize they’re hot too and that’s chapter 41! Sorry I couldn’t find the first one ╥﹏╥
Chapter 41! Tae-moon only saw Seonwoo's parents without glasses however. He still hasn't seen Seonwoo's older siblings without theirs
I saw this one panel on twitter where taemoon had a dinner/lunch with Seonwoo's family. The food was hot that it fogged everyone's glasses and that's when Taemoon saw that they're all beautiful people but looks weird when they wear glasses.
