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

These 2 series are both airing right now and they have some similarities. They are both BL comedy, simple funny and lighthearted
Also the actors are all really handsome xD
