My Esports Genius Brother (2021)

Both are mini dramas with a (censored) BL relationship and a focus on sports. The two MLs are initially antagonist to each other.

The plots are not very similar, but if you're interested in post-censorship Chinese BLs that manage to make it very clear that the two boys are romantically involved, these two are at the top of the list. (Spoiler: They both have confession scenes and the boys agreeing to enter into a relationship with each other.) My Esports Genius Brother manages to be the most overt about this, but His Cat features family support of the boys' relationship. Unfortunately, another thing these titles have in common is poor English subtitles.

Both shows are bl and have a male lead who's colour blind, they see the world in various shades of black, white and grey.

Both are short length, opposites attract relationship Chinese BLs with a similar vibe.
.........................................................

Both are Chinese BL mini dramas. The MLs have contrasting personalities and are initially antagonistic to each other. One of the MLs lives with a female relative (mother vs, sister) who disapproves of the relationship and tries to chase the other ML away.

Both are short length BL dramas in which the couple has a sort of push and pull relationship between enemies and lovers, on opposite sides at times, working together others. Both MLs are lonely, isolated from society, and troubled. One of the MLs has a sister who is his only family, and the drama concludes with the trio living together.
