Cafe

The Cafe is unlocked after clearing Normal mission 2-1 and is an important part of the game. Here, you can raise affection with your students by tapping on them or giving them gifts. You can also claim Stamina and Credits that cafe passively generates over time. How much Stamina and Credits you can generate on a hourly basis depends on the level of the Cafe and its Comfort level.

Pressing the button located on the bottom right of the image will take you to the screen with your stored Stamina and Credits and they will be added to your current Stamina and credits shown at the top of the screen. There is a cap to how much Stamina and Credits you can save so make sure to claim these before you reach your cap so your cafe can always be generating Stamina and Credits.

Visiting students
A fresh set of students will appear at the cafe twice a day, at 4:00 and 16:00 server time. While the selection of students is generally random, students (both owned and unowned) that have a unique interaction with a furniture piece are believed to be more likely to appear. One additional character of your choice can also be called to the cafe every 20 hours using the invitation ticket icon on bottom. Tapping on an already owned student will raise their Affection level slightly (refreshes every 3 hours).

Gifts
Gifts are obtained through Crafting and Events and can be given to students to increase their Affection level. Students accept all gifts but certain gifts pertain more to their story and character. As a result, those gifts will provide increased bonuses. The faces above students indicate how much they would like the gift you are currently dragging.

Rank
Cafe can be upgraded with Cores rewarded for first clear if certain stages. After obtaining the item, press the button shown in the bottom right of the image that displays Comfort rating. The icon in the provided image says 3000 which is the comfort level of that particular Cafe so you want to click on this button, then the blue button that will appear in the new window then confirm the cafe upgrade.

Furniture
Comfort level can be increased by placing furniture in the cafe. Placing matching sets of furniture provides additional Comfort bonus. Furniture is obtained through Crafting, Events and, in the form of trophies, by competing in Raids. Students that have a unique interaction with piece of furniture will always be seen interacting with it, if possible. Below is a list of all furniture items that have character interactions, for a complete overview of all cafe furniture see Complete furniture list and Raid trophies
