- Both are set in historical eras where being gay is seen as 'abnormal and perverted'. However both portray a beautiful and blossoming romance that has great chemistry which will leave you wanting more.

- They both seem to have mystery/supernatural themes which could be appealing to viewers if you like that sort of thing.

- It appears there will be obvious villain type characters which can bring insane amounts of dramas, which can be found in both dramas.

I first watched to sir, with love and found myself looking for another thai historical bl romance as i loved and enjoyed it so much and feel that i feel you linger in the air will be on par with to sir.

Both male leads played by PondPhuwin.

Similarities:
- Phuwin playing a character who is seen as a 'loner' with little to no friends
- Pond befriending said above character and trying to help them
- Sweet/wholesome romance scenes
- Love triangles
- Cute side couple (different actors in each series)

Another drama with the main couple BounPrem. Both start out in a somewhat rocky relationship but end up with a happy ending.

Both are BL's with a plot of the world ending within a few days, from the start of the series. With both main couples having an enemies to lovers type of relationship, which makes it all the more interesting as their days are limited.

Plus both have decent NC scenes (18+ ) if you're into that kind of thing.
