Wait, you can hug Harlequin?! What did I miss? ðŸ˜
Haha yes!! If you don't eat anything and accept to see Pierrot the next day (DAY 1), then follow Harlequin, and tell Pierrot to leave you alone when he comes to your room, Harlequin will come instead and there is an option to hug him.
I was so schocked like, how is that an option ðŸ˜(it's not bad, but really wasn't expecting it.
