Project S: Side by Side (2017)

Both showcase the main lead having autism with heartwarming family moments and great character growth.

Okay, so they are VERY different BUT the sibling dynamic is similiar, with a glass child and a disabled (autistic) sibling/cousin.

Basically, a sibling with a disabilty makes another sibling appear invisble to their caretakers. In other words, the disabled sibling's probems make the abled sibling's problems appear insignificant, which prompts the parent to 'look through' the glass child, instead of seeing them for who they are: a person /child with needs, problems, and mental health of their own.

This often results in unrealistic expectations, where the glass child is made a (secondary) caretaker of another child. In both dramas the glass child is younger and they love their sibling dearly but also can't help feel resentment for the needs that weren't/aren't met because of the space taken up by the disabled sibling and their problems.

It's often tragic because the ressources are few and the disabled child takes up most of them -- and the caretakers believe that the abled sibling is better off than their sibling, and thus are 'strong enough' to handle the neglect. The whole situation stems from love (and faith in the glass child's mental strength) and yet the glass child often feels either unloved, underappreciated, or invisble -- or all of the above. And they feel guilty for their resentment towards the situation because it isn't anyone's fault, it just is. The caretakers are trying their best, the disabled sibling is often unaware, and the whole thing just sucks all around.

The struggle is real and both dramas portray it well.

Both plots centered around sports and familial bonds going through a rough patch.
One is a Taiwanese movie, the other a Thai series.

Project S: Side by side is a sports drama just like racket boys. Both uses badminton as part of the plot of this show. They depict life as they build companionship with each other. It shows struggles of the characters in pursuit to be great players. Both can be heartwarming and inspires people as they watch these two dramas.

Both deal with individuals with autism trying to achieve their dreams of being athletes while being pushed forward by a strong mother/mother figure.
