You're patient enough so far. Doki drags you toward Velvet Hall, and heads immediately toward the south entrance. As you barge through the doors together, she continues to escort you to the nearest set of stairs, but there's also a dorm room that is left cracked open just a few feet away.

• Divert Doki to the first open dorm you can see.
• Push Doki under the stairwell to fuck her right there.
• Let Doki keep leading you upstairs.
