Caro Locatário (2020)

-LGBTQ+
-Secret gay relationship
-Grief
-Guilt
-Man is given a hard time by the family of his lover for being gay

Don't worry. It's just not that their names are similar.
Both films are based on the same premise where the boyfriend of a deceased man gets involved with the family of the latter and more particularly focuses on the relationship between the boyfriend and the son of the dead partner.
Also, both depict the consequences of prejudice and pressure against the homosexual community while beautifully capturing the raw essence of Taiwan.

-both lgbt focused movies that also shed light on some of the discrimination and prejudices they have to deal with
-one of the main characters is a child
-theyre both sad and emotional, id put some tissues next to me if i were you
-the endings are very similar
