Heracross is such a little sweetie! I love them too, they're so needy but they're always stuck running the shop. If you ever solve puzzles with them, and find the secret room in the shop after -- you should spend some time there and make their day 💜
I'm glad you find the sex parts of the game interesting, and I'll be curious if there's a specific character in the game that eventually resonates with you a little! I'm asexual myself and there may or may not be an asexual character in the game, it's left up to interpretation. But the game is very sex-positive and everyone in the game enjoys their time with you, so I hope you continue visiting with them to say hello 😀
