- Theme: Both shows are about soccer and coaches training passionate teenagers.
- Characters: Both have the same main characters: a enthusiastic female teacher and a talented but strange and distant male coach.
- While the characters are very similar, Go! Goal! Fighting! has less romance and focuses more on training the soccer team.

Both are from the same Author and share a universe, along with Ai Long Nhai and Tonhon Chonlatee
Although the vibes are very different... it's a nice watch.
I would recommend Wandee Goodday as a good watch either way

Both boys love shows are VASTLY different in plot, but i still feel they are a little similar. For one, the visual aesthetic of the paring is similar (one is somewhat taller, has lighter hair and is more submissive, the other has darker hair, a bit broader). Apart from this, both depict adults dealing with relationship complications and break ups. Still, the characters get (back) together.

Two people become involved with each other through online messages/messaging. Main characters are navigating love, romance, relationships, break-ups, hook-ups...
When it rains, it pours drops the online chatting element very quickly, while in Haru its kept until the end. When it rains it pours also has a cheating element and moves much quicker, although, Haru also has some complicated relationships and touches on relationship troubles while the characters gradually discover their romantic connection.

-Both are korean movies produced by/to watch on netflix
-Romance stories in which the male lead is popular and the fl is kind of strange or has a strange condition
-Healing together/eachother
-Both might make you cry

Teenage high school student with a passion for art/creating develops a crush on her/an art teacher.
Soft/sweet/calm vibes and atmosphere
Fruit has a stronger romance element, in my heart leaps up there isnt much progression and everything stays a mostly innocent crush

Both are slow burn japanese movies about two guys becoming unexpectedly close. Theres lots of underlying tension, frustration, longing/yearning, secret crushing in both and a similar kind of gloomy atmosphere.
LGBTQ content and themes

Short romcom shows with a gay romance
male lead is a late bloomer with little romantic experience and becomes romantically entangled with someone he works with
lots of likable side characters
Colors' focus lies less on the romance (especially in the middle section) but i still think its an enjoyable show

Both have similar vibes in music and eerieness.
Both have peculiar female lead
Both have romance genre

Both are short Chinese BL dramas with very similar vibes. Set in the summer, surrounded by lychees, question of fleeting romance or something more.

They are both wuxia dramas, with strong FL's and ML's.
For both the FL's come across as weak but are secretly as strong if not stronger than the ML's leads.
They are both "touch her and you die tropes".
They are also both "she fell first but he fell harder tropes".

They both are about a parent who takes revenge for their daughter which is killed. Also the daughter in both is bullied to death by their classmates where their parents finds out and takes revenge for them.

Boys love dramas with the same actors playing main characters/the same main pairing (UpPoom)
- forbidden romance
- Nc content
etc.

both are boys love dramas with darker themes, crime/solving a crime setting
the mcs start off as enemies due to being/having been on two sides of a spectrum (in Trapped one is a gangster, the other is a police officer, in Prosecutors proposal one is the son of a 'murderer' the other is the sun of a murder victim)
the characters are interested in uncovering the truth behind a case/murder
have to work together against all odds which brings them together romantically

Both are short japanese indie/low budget dramas uploaded to youtube with subs. Both feature a romance between two guys too.
Shujin-Ko, though, focuses on multiple mains and on college/university students while colors is about 30ys/40ys and more "grown" struggles.
