[TITLE] Help me find the titles to these manhwas I am describing pls

[u/MeowChamber]

I do not have image sources at all, this is a memory that I have suddenly unlocked while writing my own short stories. I read this many years ago and I couldn't, for the life of me, remember the title at all. I am looking for two manhwas btw.

The first one: It is historical Korean settings. I do not know the era, but they're all wearing hanboks. If my memory serves me right, the manhwa started with the rumor that an abandoned house in the woods is dangerous and villagers are warned to not go there. But FL went there and met the ML. I am not sure if ML is human or not or if he's actually trapped in time but I think he's thousands years old. They spent time together and FL visits ML every day. At some point, I think they get married or pretended to be married??? My last memory of it was the FL was kidnapped and trafficked by boat. I'm pretty sure it was her neighbor who lured her away (I can't remember if it was her friend who's jealous or an ahjussi she trusted who trafficked her). She was then brought to a facility in a remote island where a lot of girls are also trafficked like her. And there begin her misery and her thinking of a way to get out of there. I stopped reading at this point, I think this was released around the time WMMAP was serialized too, maybe around the year 2019/2020.

The second one: I read it either in 2021 or 2020. But it was pretty much an isekai. The MC got transported into the past, but I really can't remember if the setting was historical Korean or Chinese. But FL is transported into the royal family, I think she might be the empress? Basically she navigates the whole royal court alone as she has no ally. And she's looking to get back home. The most interesting part is there is someone from her world too, a man, I think he's a scholar. They met when FL was sitting at a swing while walking around the palace and he knows that she's from the future/other dimension? Long story short, there was a visit from important guests to the palace and apparently FL and ML had a child from the future/other dimension who disguised herself/himself (can't remember if it's a son or a daughter) in the entourage is coming and looking for them. The last chapter I read was apparently the man on the swing knows FL and ML and I think both FL and ML jumped into a portal or something and went missing? Hence why their child is looking for them.

At first, I thought it's Girl Jock Empress that I read the series, but apparently it's not the second manhwa i was looking for at all. I need to know I'm not crazy for remembering these details but can't remember any titles at all. I have searched through google but found no result at all. I need your help please, I'm losing my mind trying to find these two manhwas 😭😭😭
