Jaskier is, to the surprise of nobody, a very emotional person. He feels a lot and he feels strongly, and that's of course one of the things that make him such a good artist. He keeps his regular notebook to compose, but he also has an extra secret one, one that is almost a diary - as an artist, the best way for him to handle his emotions is through poetry. It helps him greatly to handle so any emotions by putting them into words and onto paper. They aren't the best of his writing, and he doesn't care. He doesn't write those to present to his professors in Oxenfurt or to sing in court - he allows to be silly, less perfect, just a way to take it all off his chest. He always feels more centered when he's done.

Her Sweet Kiss is a 'proper' song, one he could sing for a public if he wants to. But right now, it's working as his silly rhymes would usually do: it helps him calm down, helps him quench the flames that threaten to burn him from the inside. It's cathartic, that's what it is.

But that doesn't mean he isn't startled by New Geralt's sudden appearance. Fuck, did it hear it all?

And why should it matter anyway? Judging from what he saw in the master bedroom, this Geralt wouldn't have a negative reaction to Jaskier's pining. He's allowed to express himself... it's such a weird thought to wrap his mind around.

"I hope you know better than expecting me to apologize." He says with a little smile, watching the witcher closely for any clues about his thoughts on the song. His scent continues to be bittersweet. "My song has reached a gentle heart with its message - such an emotional reaction is a compliment for this bard! The magic of poetry showing its power! The only thing I lament is having missed it."
