I like how each name is color-coded. It makes the game more visually appealing and helps me remember who’s who more efficiently. This may be my personal preference, but when Miru and Stella hang out, the color coding stops. I'm not sure if it was because it’s a WIP, but it did catch me off guard. I do also suggest maybe breaking out the dialogue. It's a bit lengthy, so a suggestion I have is to break it up into passages.
Just to provide an example, in the following passage: "Hey! Miru! My boy! Come over here!" Called Damien the Scrafty as he was sitting next to Lara the Steenee.”
You can add an option here to follow Damien's call or not. Then, if Miru does follow, you can paste the following dialogue you already have: "I'm coming!" Replies Miru as he was walking toward his two best friends. "Miru, you gotta look at this! This idol girl is really cute! I wish I could go on a date with her!"
That way it's easier to read instead of just reading everything and then making a choice. I really enjoyed your writing, though! It’s expressive, and I love how I can imagine each action without the help of pictures!
