Thank you for your suggestions! :)
I agree that The Story of Ming Lan was good. When A Snail... was also okay.
I haven't watched the other ones, except the first episode of In Time With You. I dropped it because I didn't like it at the start of it. I felt like I had seen the topic too many times in dramas (woman turns 30, people start calling her old, pressure to get married...)
Maybe I'll try the other ones later, they seem pretty good! What I was looking for this time, though, was something without the comedy tag. I wanted something very calm and quiet and more towards slice-of-life. :)
