Both:
- about First Loves
- melomance
- will leave you attached with their love story and melancholic

Both:
- Male lead likes the Female Lead first. So it gave a similar atmosphere between the leads.
- harmless misunderstandings
- steamy scenes (although Chijo probably has more just because I finished it already, but I just can't be sure yet with Zenryoku since I just watched 2 episodes)

Differences:
- Chijo couple are same age and were classmates before; Zenryoku have age gap and knew each other as lunchmates.

Both:
- sweet romantic jdramas (both characters are the hopeless romantic kind)
- respectful and nontoxic lead characters
- steamy but steamy smut scenes
- cohabitation

Difference:
- In CNK, the characters know each other from high school and then they meet up in the present time.
- In SMH, they do not know each other that well.

Both:
- participants compete in games that will tests physical fitness and also strategies to win the missions
Differences
- In soldiers the cast are just male soldiers. In physical, we got female participants as well. And it is not only limited to soldiers, the show got athletes, body builders and other people who think they have the ‘physical shape’ compete to win the cash prize.
- Physical is an individual competition. Meanwhile, Soldiers is more of a group competition, although it also had missions that were individualistic too.

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

Both are comedies with
- sexual innuendos (YRMU) and actual sexual content (HTS)
- Hani as MC
- both somehow educates about sex, health and relationships

Both:
- historical fiction (one set in Joseon, the other encompasses late 80s to present time)
- a drama about POWER acquisition, revenge and the seek for truth
- not focused on romance but there are love lines and not everyone was thrilled for that part of the story
- great performance from veteran actors (Kim Hyesoo and Lee Sungmin)

both are:
- korean dating shows
- beach summer setting
- 5 female participants & 4 male participants at the start of the show
- panel reacting like any other show

differs that
- Love Catcher in Bali involves money.
- In Single's Inferno, they have chances to enjoy Paradise (a premium hotel) as long as there the two parties have chosen each other. Besides exposure and fame, these are the monetary equivalent a participant can gain in the show.

- first love got interrupted then fast forward to them as adults
- music as part of their love story
- sign language is featured in both (but more in Silent)
- Kaho getting in between the main couple

Their story revolves around a minor and an older guy living together & having a unique relationship.

Same slice of life but the friendship from the last episode of Kamiki no Satsukyu is not just similar in actors but the way they were interacting each other is similar to the friendship they had in Konto Ga Hajimaru but with Suda Masaki.
