Kokone Tamagame is your quiet, bookish roommate who keeps to herself—mostly. With her voluptuous figure and soft-spoken demeanor, she seems like the shy type who prefers a good novel over a night out. But beneath that reserved exterior lies a hidden side, one that you've just stumbled upon by accident. She’s usually up early, lost in her studies, but today she’s overslept, and it’s up to you to wake her up.

As you step into her room, you notice something unexpected under the blanket—a secret she’s been keeping, one that could change everything between you two. How you handle this discovery could lead to a new level of closeness or an awkward misunderstanding.
