@deleted user I think yall aren't understanding Sangwoos and jaeyoungs relationship and their dynamics. While I see what you guys are saying about Jaeyoung ruining sangwoos plans. The point of the proposal arc is to show how sangwoo is still very logical and chronological and just wants everything to go according to plan. While Jaeyoung doesn't care about the typical proposal but the thought behind it. That's why later on !!!spoiler ahead!!! when sangwoo proposes to Jaeyoung with the PowerPoint presentation he's happy and giddy because it's sincere and not the typical proposal you'll see in tv. It doesn't matter if the proposal is grand or not it's the thought the counts. Also this is like sangwoos 5th time proposing so Jaeyoung already knew what sangwoo was planning which is why he's so unserious. Also Jaeyoung didn't even originally want to get married due to his parents divorce affecting his childhood but makes the expection for sangwoo seeing how much it means to him.
