Water Boyy (2017)

While not really the best out of the Thai's, there are similar treads of coming of age, leadership, swimming, and friendship.
The differences come where the Thai story is, of course, a BL

Both are BL series where one of the characters has a girlfriend and struggles with coming out. They also go beyond the norm in showing affection, even though Water Boyy has only *spoiiler* one real kiss. Also, they have other characters with a story of their own. Plern Pleng and Waii's girlfriend act similar (but Pleng is actually a villain). Both deal with BL in a more mature way than usual too.

Thai BL dramas. Not many similarities but part of the story in UWMA revolves around the faculty's swimming team (more predominantly in Water Boyy, of course) both series have a swimmers BL couple. If you like boys in pools, watch them both :)

Earth Pirapat playing as a swimmer with most of his scenes being shirtless by the pool.. do I really need to say more? Victory Lap is not BL but you might want to check it out :)

Themes of love, team spirit, team work and interactions with friends and everyday life. Similar water, pool based sports.

Similar themes of forbidden love with parental interference, hope, family life and school life interacting with personal life

We Best Love: No. 1 for You features swimming as a sport and so is Water Boyy. Both series also have BL elements of a drama. Both of them also feature cute main characters in a school setting.

They both are Swim team Dramas, however the ''movie'' was a older version lets call it the original, and ''water boyy'' is a updated version, Now my opinion is that the characters were great and the chemistry was well scripted and the actors did a great job of conveying there character as if they were real people . A much more comedic feel that you can get that feel good factor while just engaging in the plot and letting it all sink in.

Both have BL.
Both male leads do not like each other in the beginning.
Both male leads eventually fall in love.
