Mhmm iam not sure......

What was the reason, for her to ask him give that handkerchief to blondie!?
What people don't understand are the small details in this story.....
Like the importance of those hickeys, who's the one she's trying to make jealous!?
Does the handkerchief hold any significance!?
In the last panel when that crying girl said, "she did it for her sister" who's the sister here, the one blondie marrying or singer lol!?

So iddnt add those things to my explanation cuz uam currently looking for raws of this manga and i cannot find one, and i am also confused how and why i am also waiting for new chapters

Oh I see, didn't know there were more chapter, thought it was just oneshot!!!

Theresa is the black haired girl playing Cherubino. The blonde girl, Agnese, is her sister. Agnese asked Gepetto to give the handkerchief to Theresa in the green room. It's not said directly, but it's implied that Theresa planned this so Gepetto would see her with Jean. No one is getting married. They are singers in a famous opera named The Marriage of Figaro. At the end you can see that Jean's scar is shaped like a ring + the song lyrics, which suggests that the one Jean has the strongest bond with is Gepetto not any of the women he's messing around with (which leads back to why Theresa was jealous of Gepetto and created a situation where he would see her with Jean).

Thanks alot for explaining!!!
