- Mafia and Crimes Vibes
- There's fighting scene
- Strong male lead
- Clingy male lead
- The exact love story, from not knowing each other > getting to know each other > liking each other > from liking to hating > from hating to forgiving > and became lovers again! ( the differences is LTNS is too short so kinda faster, and J&J is too long so it's slow burn )

- They two have same language, Thai
- University/school setting theme
- Love story between Senior-Junior
- they had same story, Coercion from Senior to Junior in episode 1
- Junior had Hate-Relationship with Senior in first meet
- and the others similarity waiting for the next episode

It' school based and love-dovey with slow burn. They give me cutie-vibes with their chemistry. They have the same problem which is lack of communication & not knowing they inlove with each other. The story is flat but in a good way ( *flat means there's no major problem or problem that change all situation )

The vibes it gave has similarities like baddass characters, strong male lead, fighting moments and crimes-story. Even the path is different ( H3-trapped is more police-mafia lovestory & Jack & Joker is more debt collector - pro stealer lovestory ) but still they gave mafia vibes with enemy to lovers plot

- School background activity
- Friendship
- great story with happy ending
- had handsome actors
- the acting is incredible wow
- and much more ( the difference is bls & bromance )

I think this series is really similar because they love music & have great OSTs. They also have BLs story and goes by with music and be boyband together. And they had little angst story too( on second cp ) but ended up with good ending ( second cp being together at the end ). That's it:-)

- Using Chinese language
- School background
- BL story
- Friendships
- Clingy Boyfriend thing
- the one of main character had parents that don't care much with their son ( Parents who just think about themselves )
- Family problems
And much more, i guess:-)

-Using Chinese(& that from China Mainland)
-Bromance
-High School Activities
-Brotherhood storyline
-Enemy to Friend storyline
-Friendship
- Web Series
-No Romance( just a bit, because more Bromance scene. than Romance)

That's it

- School background
- the story relates from the relationship between the main actor and his parents( they both had problem w/ their parents )
- main character is supported by a good friendship
- they both using Chinese
- have the same title
- the story same tells about finding the identity of the main character

The difference between About Youth & Youth/the newcomers is About Youth's from Taiwan ( ofc is LGBTQ Romance ) and Youth/the newcomers's China mainland ( ofc is Bromance because LGBTQ series in there getting banned ). That's it

It's not really quite similar, but this two are masterpiece in School Story, Friendship Story, Slice of life, Going holiday with classmates, from strangers to be friend, and much more similarity. The difference is ReLIFE it's more focusing on love story, and the Youth 2022 ( "The Newcomers" it's officially title in YouTube YoYo channel ) it's more focusing on bromance main lead story. It's really worth it to watch them 2 because chemistry are out the box(^o^)
