"What do you wish for?"
"Read my heart."
"What do you sacrifice?"
"Read my soul."
"So be it."

We don’t know exactly what Gabriel asked for - all we know is that he sacrificed his life for Nathalie’s. But what if his wish also contained a hidden request for Adrien to become a real human? Isn’t that what his heart might have truly desired?

Adrien is not a sentimonster anymore!
Look 👀

In the episode “Werepapas”, Ladybug breaks the ring, but there’s no amok inside, even though we know there should be. In the episode “Yaksi Gozen”, a bird lands on his hand and… nothing happens - Adrien doesn’t have allergies anymore.

"If someone wished for garden peas to turn red, then strawberries would have to turn green"
 
So if Adrien turned from a sentimonster into a human, then who turned from a human into a sentimonster?

Hypothesis 1 - Lila
Perhaps the blue light in the Season 5 finale is a clue - maybe that’s when some kind of magical transformation took place…

Hypothesis 2 - Aglae
The entire fandom noticed Aglae’s resemblance to Lila - her face and her sudden disappearance from Alix’s party. But what if Aglae is actually the sentimonster now, under Lila’s control? Moreover, Aglae is afraid of butterflies - perhaps it’s something similar to Adrien’s allergy?

But here we have some doubts again:
1. Why did Lila get such an “ally”? - maybe the blue light and that whole scene can explain it to us.

2. Where is the amok? - I didn’t see any rings or other jewelry on Lila’s hands. The only thing that comes to my mind is… the pen. The pen she uses to write everything down in her notebooks - all her observations, maybe even Aglae’s experiences, everything she wants Aglae to know. If holding an object with an amok lets you control a sentimonster by giving orders, maybe writing things works in a similar way?

Hypothesis 3 - someone else, or someone we don’t know yet, but will find out in the future.

Maybe someone has noticed small details that could prove or disprove this theory - feel free to share your thoughts.

Gabriel's wish - we missed something
