But that's such a common fantasy trope, though. Not just in video games but in movies too. How many "teen beat" movies feature the whole "cute childhood friend who was under your nose all along" plotline?
Yeah, perhaps the "childhood friend" thing is played out, but it will never die. Especially in the realm of love adventures. Every love adventure needs the trophy girl, the childhood friend, the moe klutz, the tsundere, and the wildcard (sometimes it's an older woman.)
Then again, JRPG romances always end badly. Think about how many JRPG protagonists still have both parents. When a JRPG couple hooks up, one WILL die.
