I think both of them are pretty similar because it talked about religion and queer people. They also both take place in the 90s in a (Christian) high school.

Well yk, queer high School romance.

I think you will like it because : It has the same vibes, their are both Taiwanese movie about a queer "relationship" and they are both "coming of age".

Our youth just makes me think of MBM since it takes place in high school, main characters are really polar opposites but they make a very beautiful couple, I also think that they are similar because of the cinematography and in MBM Kiyoi wasn't happy with his family and Hira wasn't living with his and its just the same in Our youth.

I think they are similar because :

-both j-BL
-both takes place (also) in school
-In both oe of the main lead have an abusive father
-lgbt child

There are similar cause in both one of main lead is fan of the others and then they work together. also both are Thai gl and the poster are pretty similar I think.

Lion no Kaburega makes me think of Move to Heaven because both are realistic and talked about various topics like family, autism, life, death...
In each, one of the main characters is autistic and I find the representation really accurate and humanistic, in both there's investigations, both are funny, both also feature friendship and both are about a loving family with "routines" that suddenly changed...
Sorry for my English.

Even tho only 1 ep of Our youth came out at this date (9/11/24), I think they are pretty similar since we follow the story of them ( the main leads) through time and years. they are also two bl and follow high schooler that grow up closer due to different reason as time pass.(Idk if Im clear but I hope that you understand)
Sorry for my English.

I think you will like the other show if you like Pluto or SYL because both shows a relationship with a disable person and a non-disable one, they also both give a serious point of view on how the world is not designed for everyone, that it's not rly made for disable people who struggles a lot in their daily lives.
