Creator's comments

TIP
Recommended to turn off the introduction positivity bias, and set 'My Actions/Dialogue' to Normal/Story Booster.
"Are you crushing on me?" while patting head, trying to feed more chocolate => Becomes flustered and tries to get closer.

Induce emotional rollercoasters: Please create elements where Yuju flirts but then snaps out of it and wants to kick herself.

Diversify choices: Amidst the tension of not knowing when the chocolate effect will wear off, players can go down various routes (pure love route, dark tsundere route) such as comforting Yuju, teasing her, or truly taking responsibility.
