Thank you for playing! I'm very glad you enjoyed the game overall! It really means a lot hearing that, as an asexual person myself.
In terms of the story, I can understand where some of your confusion, concerns, and critques come from. Yes, Seo-jun and Iris do have sex, but it's at his discretion. If he doesn't feel comfortable, they won't have sex. If he ever gets uncomfortable during intimacy, they stop which is alluded to when they talk about communication. It's at his pace, etc. I think I could have elaborated on this better like you said. When I dive into Seo-jun's story in the future (and produce more ace content in general), I will be sure to make to make his feelings on sex more clear. Thank you for your feedback. :) 💜
However, I want to make this clear: just because you aren't able to fully relate to Seo-jun does not take away your validity of being asexual. You are incrediblly valid! If you want more ace stories, I strongly suggest browsing some of the VNs in the asexual tag. There are plenty of stories about asexuality with characters who I believe you may find a stronger connection with! (https://itch.io/games/tag-asexual)
