Did you check on 4 panels? items are classified into 4 different categories, drinks are the 4th one. But I'm guessing you already know that you can just talk to the girl and if the item exists she will automatically fall into your arms. Did she react to the item? Please let me know what version are you playing

Ok, you can try to delete previous saved files here:
C:\Users\your_user\AppData\Local\ZIsland\Saved
Replace "your_user" with your personal folder and delete all files in \Saved folder. Might be something wrong with previous saved game. Please contact me (jptester) through Discord to look deeper into this issue.
