Brothers (2021)

Thai BL dramas. Both take place in highschool and most of the cast is young. Includes different storylines within the school and the leads have a extroverted/introverted kind of chemistry.

Story kinda same. Like his father remarried. He don't like his step mother and brother. Brother room shareing.

Like the characters Hida and Saint, the two leads in "Brothers" are stepbrothers by marriage. They start out as enemies but eventually fall in love.

Another nice BL drama in high school life that follows several gay relationships with familial implications.
And also, there are two twins male actors in the secondary roles.

Both have similar content like brother love. Step brother relationship. Parents remarriage etc things
