I’m so confused with the timeline

Way back in chapter 1, it’s said that Mujin is 33, but he told Wuyeon he’s 30, so either the first chapter is in the future and this has been going for 3 years, or he lied about his age to Wuyeon. Also in chapter 1, Jun tells Mujin he *knows* he’s been going to that building to see his wife, and Mujin freaked out, but we know from chapter 27 that Jun knows that Wuyeon is the “wife” and Mujin knows Jun knows, so then that scene from chapter 1 makes no sense. We also know that Wuyeon had long hair when he first met Mujin, and Mujin was the one who cut his hair, so going by hair length, chapter 1 happened after their first meetings. Unless the shaman has the power to wipe memories, I’m very confused about the timeline.
With all that being said, I was surprised that the kidnappers weren’t originally the dad and the shaman.
I’m positive nothing’s gonna happen to them and they’ll eventually get their happy ending, but I do think that they’ll be forced apart for a bit (which brings me back to chapter 1 when Mujin goes in and sees the mess and he’s jumped by Wuyeon who complains it’s been a while, does that mean the dad won’t separate them because Wuyeon will threaten to harm himself if something happens to Mujin?)

Why do I ge the feeling next chapter will be the season end?
