I just listend to INI's debut album and looked trought the lists of who produced their songs and ...
As like in the Japanese artist Orbit a bunch songs are co-produced by Moon Kim o.o
For thos who don't click their brain reading that name:
Moon Kim, realname Kim Moonchul, 33 years old, is a Korean vocalist, guitarist and and producer born in Incheon (Korea) who grew up in Los Angeles (USA). Moon originaly was in a band with his brother called Richard aswell as two other Korean member called Sooyoon and James who often apeared on street festivald in LA. Someday the band was discovered and taken under contract and than debuted in 2013 in Sputh Korea, but without Moon's brother since Richard had passed away in 2008. The band was called Royal Pirates
I don't know if the band still exists, but after James left the band in 2017 it became very quiet around them. Moon had around that time (or a bit earlier) released a few solo tracks and I didn't heared of him or the band ever again, since his name randomly poped up on the producer-list for a bunch Japanese songs.
It's very interesting what way some people go and I never thought that someone like Moon would ever become producer for JPop-songs tho.
Here are the Japanese songs Moon co-produced on:
Outide of this, Moon also worked on a crap ton of KPop-stuff as for example "Beautiful Beautiful" by ONF, "Miracle" by GOT7 and many more
