Great to see a fellow OG LiS enjoyer! I still get heavy goosebumps over the OST. Santa Monica~
I don't really have proper ships in that regard that the only games where I began shipping were animu ones, where an official couple doesn't exist in a canon sense.
Shuichi x Kaede. For the ship fandom this is considered as the "official" couple, but if you played you know why this is the favorite. Clair de Lune....
