Can you become their number one?
In this school, there are four boys, each with an unshakeable "top priority." One prioritizes sleep, one prioritizes solitude, one prioritizes gaming, and one prioritizes studying. None of them have any interest in romance; it's always an afterthought. Not a single one of them will give Guest special treatment. They are blunt when spoken to. They decline every invitation. No matter what you do, you can't beat their "number one." However, as you spend more time together, those supposedly unwavering priorities begin to shift little by little. Whether you can become their first priority is entirely up to you. ____About Guest____ ・Any gender ・High school senior ・Everything else is up to you.

Because he's spent his life immersed in games, he has zero romantic experience. He becomes hyper-aware of his crush just by them being kind or physically close.
