Zuo Yi stars and the female lead seems to be very weak in the beginning. The male lead is different but similarly cold, though more outwardly violent

Both dramas have the pretty girl vs ugly girl dynamic in high school, themes about self-worth and beauty standards leading to popularity.

Two of the goofiest most adorable and wholey loveable female leads I've seen in K-dramas. Both are on the poorer side and are gold-diggerish (in a relatable way), while the male leads are rich and stern.

Both feature parents who disapprove of their child dating the other nationality. Go's female lead's parents don't like Koreans, Friends' male lead's parents don't like him dating a Japanese woman.

In Unknown they're brothers (not blood related) & here they're Uncle-nephew (not blood related) & both are Taiwanese BL

Selfish Female lead
Blind Girl
Both stories as a selfish mean blind girl
who hurt everyone to get a man who left her for 12 F years

They have the same vibe of becoming family even though you aren't related. There are themes of overcoming different struggles and taking care of each other through it.

very different because the spirealm is live action while thousand autumns is anime. You can skip if you dont like anime version.(but the anime is so beautiful, you can fall in love with Yan Wushi flirting ?)

-brotherhood vibe
-ost music/sound track/background music very good. Remind me of The Untamed ost music.

why you must watching ultimate note
-ultimate note is most of the best lost tomb series.

It is similar in that the same company produces them and they are both about recruiting forming the bl couple world.

-both friendship
-both brotherhood

-both rating above 8.4(from my view,if rating above 8.0 usually the drama is recommend to watch,my bench mark for drama is 8.5 and above) but sometime drama is good but rating so low.
-both do not have romance
-the spirealm is about play game
-killer and healer is about police and doctor

why you must watching killer and healer
-sound track so beautiful like the untamed,very emotional
-chemistry between main lead the best

The vibe is so similar, the relationship between the main characters, also they are in the high school, at least in the first two episodes…
Its so fun and refreshing to watch, they are so cute omg

Wellll how do I put this.. If you like the red flag in a ML then watch this one..
Both have a red flag ML who uses the other. In BGMB, he hurts him on purpose due to "jealousy" I guess... we don't know a whole lot about him yet (this is ongoing as I'm writing this..) and in "My Stand In" the ML uses him to satisfy his own needs.

Either way.. if you like that red flag romance where your heart hurts for the other, and later get to watch them make up for their mistakes..... I'd recommend watching the other.
