There's nothing wrong about asking. Proper NSFW scenes will start in the next update and new ones will be included in every update from then on.
Thank you very much, maybe one more question. Would you make any scenes for same gender characters? (Such as picking Lumine and dueling Beidou, or picking Aether and dueling Chongyun)
That's the plan! Both twins will be compatible with any character you choose.
