Yeah I not sure if it is a translation issue or what. Remember she is getting a "bus ride" from Woohyeon so she was probably supposed to meet him in the dungeon so they could form a party and then he would carry her to allow her to farm XP. Then afterwards she was going to make him a birthday dinner to complete her quest. This is what I think is happening but hey I could be wrong.
@Kagome It could be the translation but I'm getting the impression that the producer/artist is following the LN and skipping scenes without realizing it. There are quite a few moments where it really feels like we are missing chunks of the story vs translation issues. Not sure if I'm right but I feel like I've read enough poorly translated stories to get a good sense of the difference between those two things.
