Thanks for stating this! It does indeed function as a introduction to the date mechanics. BUT for v0.15, there will be a little rework on the current scene by giving a actual choice. Which can lead to doing the mechanic introduction with a man...building up to a spicy reward (as in the current female route).
No worries every content will be treated equally!! It was totally my fault to force the player to date Kaori even when the sexual stuff can be refused, sorry on that!
