Uncle unknown is also a Chinese short drama consists of 12 episodes.
Both dramas are web series.
"Stealing from my Ceo" is 2 mins longer while "Uncle Unknown" is of 7 mins.

Phupha| Nanfah is the Thai prequel to "The Promise"
You can skip prequel and watch the sequel for better understanding.

Since Loud was a survival show to produce a boy band and I-Land was also a survival show to produce boy band named "Enhypen" so I find is similar since the object was to produce a boy group

This series is divided into 3 parts
En Of Love: Love Mechanics
En Of Love: This is love story
En Of Love: Tossara
So I think these all should be in recommended list

They both are university dramas and both dramas have love triangle so I find the genre similar ofc story is different
