Both are mini dramas with a ML who is visually impaired (in some way) following an accident that was later discovered to be intentional, and a FL who enters his life under false pretenses. Both leads are in a form of design (perfume vs. jewelry).

Both are mini dramas with a visually impaired ML and a FL who enters his life under false pretenses.

to me this drama has a similar vibe., as in how they use their scenses. they main characters, will work together.,

Aside from being both dating shows, the sand wrestling episode of Love Alarm reminds me of Single's Inferno. I wish they also made a small pool with water too because wrestling in sand looks so painful.

Both are mini dramas in which a real world person enters a story and falls in love. Both have almost identical endings.

Boun and Prem both star as supporting characters in this drama. Although it is not supernatural, it does touch on some magical aspect to it.

Both Kdramas are about agents, and the vibes are very similar. Terius Behind Me is about a single mom who somehow gets involved in top secret missions. The K2 similarly involves secret missions. Although The K2 is more about a wealthy girl and a bodyguard, like Terius Behind Me, it involves a love story around the main female character and the bodyguard which is why if you liked Terius Behind Me, I strongly recommend watching The K2.

I personally watched The K2 first and had been trying to find a drama similar to The K2, but after years and years, I finally found Terius Behind Me and definitely don't regret watching it.

Both are:
- dating + survival + game show that involves money
- cast in both programs seems well-chosen ; attractive female participants and buff guys
- good 'storytelling'
