Click the icons on the right to make bubble tea. Click the drink button to drink the tea. If it says 'too many bubbles' you just need to drink the tea. Note: I wrote Japanese symbols, then saw on google that bubble tea is actually Chinese. I didn't redo them since they took me so long. Really sorry if this offends any Chinese or Japanese people. Please report any issues in the comments <3
