Let's start with the good (no spoilers):
I love phuwin and neo as brothers: it's so silly and their dynamic really does feel like they're brothers
i also adore louis and pond as brothers: i really did not expect it but it's very cute and very different from phuwin and neo's pairing as brothers which makes a nice contrast between the characters.
i also adored neo x louis but that's because i also saw them in the eclipse together. seeing them here as a more silly and innocent couple made me laugh a lot (iit made up for the time i wasted with pond x phuwin)
the ensemble cast of neo's friends was great: i loved how they gave phuwin's character advice and helped him build confidence.
the supporting sidecharacters were tbh the saving grace of this series because there was nothing enticing about the plot of this series.
i liked louis' voice for the ost and mix too!
the bad:
everything else. Especially the story for the main couple. there is no valuable message or meaning that FUTS wants to convey to its audience and instead just tries to throw a mix of well-known faces at you and hope you don't see that the characters have no chemistry with each other, the script is corny and cringe and the drama is unoriginal and bland.

(spoilers)
oh gee another jealous ex-girlfriend who stirrs up drama at the end? who would've expected that? not me!
besides: wtf was up with the weird fan shipping thing??? i get that they're supposed to represent irl BL fans, but in the end in FUTS the shippers get rewarded almost??? like there are no consequences AT ALL for their invasive and obnoxious behaviour.
instead of spending time on the shippers, they could've spend more time on developing Mix' character or Mork, yk the actual love interest? all we know about him is that he's the best friend of mix and madly in love with Pi for years. but where is his personality? Like let him be funny, let him be actually caring and thoughtful towards not only Pi but also others, because he wants to be. LET HIM HAVE OTHER FRIENDS AND HOBBIES INSTEAD OF ONLY CHASING PI!!!
also i must say: i don't think pond acted very well in this series but im going to blame it on the script and directing bc this story just sucked and im sure he can act and isn't just a pretty face.

final verdict: don't waste your time. watch a different series.
