Lost to Light

Judging from the trailer, Lost to Light seems to take a lot of inspiration from Gelboys (not that this is a bad thing. If you really enjoy that vibe, either series may appeal to you). The ost is very similar with these gamey, pixely, retro beats, the asthetics are similar, there are several scenes taking place on trains or big city squares, the two main leads meet accidentally and later encounter eachother again.
The main character is part of a music group (im Gelboys hes in a band, in Lost to Light hes part of an idol Group) and has spikey hair.
Both shows also feature idol culture/idols/idol music in general (in Gelboys e.g. the main characters are fans of different idols, attend concerts, collect merch etc..).
Multiple couples in both.
Gelboys season 2 features established couples as it is the continuation of Gelboys.
Both shows will be released in 2026
