SOTUS

Both are cute BL series
Both have the Junior/Senior relationships
Both are set during university life
Both have the University Moon thingy
Both have Pink Milk (Idk it felt right to mention xD)
and Both are just production perfection
You wont regret watching :)
The acting is perfect in both and the story lines may be a little different but still gives you the same feel

About university students/ campus life
Similar threads of love/ life/ social life

The plot is similar where the freshman falls in love with the senior and tries everything to make their seniors fall in love with them. Both are engineering dramas but different flavor since SOTUS is a BL and Love Senior is a GL.

Has a similar plot of a freshman engineering student during the freshman's hazing stage of school falling in love with a senior engineering student. The freshman tries with all of their might to get their senior to fall in love with them as well.

Honestly the first serie that came to my mind thinking of similarities is Sotus.
The plot can't be more different but there is a kind of magic that I can feel since the very start that only Sotus gave me at the time.
Same for the chemistry, as it was for Krist and Singto that just being near each other was enough to make you feel the tension, the sparkle abd it is the same between Bright and Win
Plus they are both from GMMTV that means some of the actors are in both series plus the priduction value is better than BL from little company

There is lot of cold war before. But then true LOVE pops up , however the only difference is ex boyfriend coming back.
So it also match with love by chance .

Both Theory of Love and SOTUS thrive on slow-burn tension where emotions build before words do.
They explore power dynamics that soften into mutual respect and quiet devotion.
Love is shown through restraint, growth, and small moments that hit hardest.

The main leads banter with each other in the whole series in a similar way.
Rak Diao or One love is an amazing sitcom with love hate relationship

Well they both give off similar atmosphere I don't know why. They shouldn't be really compared together but I can recommend you to watch it. Both of them are sweet and sometimes stressing. Sotus is more focused on the two main guys while love sick shows more stories of people. Both worth watching really.

I love both series a lot. Both series give the viewer a similar feeling while watching, because they have a unique plot.
With both series I had to smile a lot because the characters are so special and many moments are sweet.
The series are similar in structure and transferred feelings.
There are lots of facial expressions!!

Quite similar romance setting between the leads - one likes the other one-sided first while the other did not think about dating a guy before (If this contains to much spoiler, please let me know)

Some of the same actors as Honey Puppy 1 & 2. This was an amazing show with a great story. If you enjoy BL the main couple is gay, no background, half-hearted love story where the couple never gets to be happy.

I thought about it because in both, one of the leads (Moo and Kongbop) are very flirty and I saw a lot of comments saying that Moo remind them of K !
Also in both, the leads are two years apart.

Similar plots about developing love and relationships. While Grey Rainbow is a little more, well, grey, SOTUS is more upbeat and positive. If you liked the other you will like this one!

Basically you should watch sotus (and sotus s) before watching Ourskyy. Sotus provides the background context for one of the episodes and is the backstory of their whole relationship. While you can watch them out of order, I would highly recommend watching sotus first: it's way cuter knowing all the background information. The episodes are all on youtube with english subtitles
