Since this webtoon has finished a month ago so maybe this is not a spoiler anymore. This is the summary for the last chapter. Yes they had a confrontation and big bro Tae Gang asked her out. A year later, they got married. Within that one year, Da-Ae’s memories are slowly recovering, she remembered when they went sneaking up her sister and almost got caught. But she still didn’t remember her own wedding and Haneol said it’s okay since it’s only one year so it’s a good progress. Then she suggested to have a ‘remind wedding’ but Haneol said they just had their first anniversary, so they both agreed to do it on their second anniversary. The end. And yeah, we didn’t get to see a glimpse of this scene, not even on side stories. Well, I guess I have to move on.
