Could we have an option to divorce? I know this is not a decent thing to do, but y'know, gameplay wise it kinda makes sense.
Also, R18 contents seemed too generic and non-interactive right now. The idol in R18 CGs could have layered facial features, hairstyles and clothing just like the standing pictures. And we could have more choices, routes and varieties in terms of R18 scenes and gameplay. I know it's not a dating sim, but it's always nice to have everything as detailed and developed as possible if decided to be implemented in the first place. The variety of aspects, possibilities and gameplay functionalities is one of the biggest strong points of this game IMO and I rate this game above all other similar titles simply because of this. I'd love to be surprised even more.
Edit: Some new thoughts. It doesn't make sense that the songs can't be produced simultaneously by the producer, manager, coach, etc. This is not realistic. Also, the collection of idols can be further expanded. After a while it gets pretty repetitive at current state.
Love the new stories and dating system tho. Keep up the great work.
