- 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^)
