Yes, the maid, whom he helped and took in to work in his household when he was a child. Why she drugged him? Cos, she adores him and want to be with him. But besides him not being interested in her (the maid), his grandma wants him to get married since he has reached marrying age. By poisoning him into stupidity, no noble family will want to marry their daughter to him. So, she will always be the one by his side taking care of him...

Don't know why "Signal" was mentioned since this has nothing like the fantasy phenomenon stuff seen in Signal.

My guess (no spoiler here, just my guesswork):
This is about his soul, having left his body during their accident, is now dwelling in the mountain, and is the one sending out signals to help those trackers and hikers lost in the mountain....

You must also watch her in the 2012 "The Thieves"

After many years of stupidity, his normal smart self first emerges after FL drugged him with sleeping drug on their wedding night. She got her master to eliminate the poison in him. So, by the last episode, he's already cured. During the beating punishment by the drugged grandma, his head was injured but wasn't serious. He feigned stupidity to set trap for the villain.

forgot to answer your question on the last episode. If you still need to know, here's my understanding

Surprisingly, quite enjoy this one. Binge watched all 36 eps and its movie sequel

Glad to hear that cos i'm quite irritated by the sight of the scheming and uninvited guest who keeps popping up everywhere out of nowhere!!!

Seems he has gained much weight since 2019 Buried City to Shut All Lights. A far cry from the slim handsome master in the movie.

gosh, as though there's such stupid woman in this world who doesn't know the underlying interests a man has with all those obvious actions!!! Or is she just simply playing fiddle and stepping on two boats with one being the spare tyre!?

LOL, in #36, the seawater in the background is so choppy. Yet, the two talking on open deck can be standing so firmly still and without any wind blowing onto their face!!!

It's pretty common for FL being much older than ML. Seen such age gap in many romance dramas already.

he's been poisoned into stupidity. If you like light fluffy romance, this short 12-parter series is quite enjoyable.

not alcohol It's after going into slumber by sleeping drug, his normal smart self emerges.

would have been a perfect 10 for me if they were to include a wedding scene for the CP.

she didn't accept his proposal. She just wants to continue dating and not getting married.

thanks, i've watched the full #18 on Dramacool.

well, i won't say that's incorrect, just that the narrative omitted the first 10 min of Ep# 1 and dive into the main plot.

the above narrative is correct. The last two sentences will occur in the 2nd half of the story.

hahaha, dead fish kissing cos' she can't see herself doing and directing it well while in the kissing process!!!

So, how did it wrap up? From YT clips, seems like FL didn't accept his marriage proposal.
