I personally don't mind that mc's ex haven't seen them together cause the more time she spends with ml they will become more close and connected but the moment her ex saw them he will definitely try to interfere in their relationship so it's better they grow close to each other first cause the regret later will be soo satisfying as he will know that he cannot intervene in their relationship anymore and he lost something precious and she is now happy with someone else by her side.
I've been wanting to see mincheol alr see them and how she is enjoying herself but not anymore cuz of you ╮( ̄▽ ̄)╭ i was really looking forward to mincheol suffering that i didnt think of the consequences of him appearing too soon.
