Both shows are BL dramas about sports. A Perfect Match is a Taiwanese BL about a pair of tennis players that becomes a couple while The Rebound is a Thai BL about a basketball team with 1 main couple.
The side couple in Love at 7-11 has a similar plot element of taking care of a child. I don't think there's an official international release with English subtitles though.
Both have sport as a main theme (even if it isn't that important in APM), we still have a love/hate relationship with cute main actors <3
APM is more explicit then ASTCO
APM is taiwanese while ASTCO is korean
