Most otome (especially non indie ones) with a defined Mc don't really have much POC representations (outside of japanese rep in japanese otome) for the mc so i feel like for self-inserters it's just easier when the MC doesn't have a defined appearance and is nameable because we're not all pale...
I used to try to learn japanese to play Diabolik lovers but eventually i gave up and just played with the tumblr translations and the english patch ദ്ദി ༎ຶ‿༎ຶ )
