Honestly, I hope there will be a bit more racial diversity by the end of the game with the addition of new townspeople. At the moment, the town is almost exclusively white.
The only non-white romanceables, so far, are Miss Okita (Asian) and Miss Dewitt (Black). Oh, and fish girl Aqua if you're into that sort of thing.
The latinas, Lopez and Martinez, in the locker room may become future possibilities as well as Rhonda at the pool.
Compare that to: Mom, Sis, Aunt, Judith, June, Eve, Mia, Helen, Mrs. Johnson, Angelica (not really romanceable atm but she has scenes), Principle Smith (same as Angelica) Miss Bissett, Cassie, Ivy, Roxxy, Becca, Missy and Crystal. Oh, and Roz, if you're into that sort of thing as well.
That's like a five to one ratio of whites to other races. Rhonda's mom/(sisters), Tyrone's mom/sister(s), Miss Dewitt's sister(s)/daughter(s), Miss Okita's sister(s)/daughter(s), Lopez's/Martinez's mom/sister(s), Maria, Liu Wang and Yumi would be nice to be added to the game or made as an option later on down the line.
