You write Adrien angst so beautifully, I'm politely requesting:
Adrien and Luka, Adrien is going through something and he doesn't want to be alone, so he goes to Luka (as Chat or himself, phone call or on person) for a little comfort.
The trip to Rio takes an hour - it's quick. He's quick.
Plagg has given him wings to fly.
He doesn't know what to say when Luka opens the window. He doesn't even know how to start. The weight of it feels like it is choking him.
He sees Luka see it, sees the moment he shifts and prepares to receive him - no judgements, not urgent apologies, no lies.
Still - he has to be sure. "Did you know?" He chokes out, his voice breaking around the worlds, his heart shattered.
"Know what?" Luka asks, and reaches for him.
He has to be sure. "My father." He whispers. "Was Monarch."
Luka's face cycles through several complicated emotions, pained comprehension is what he lands on. "I didn't."
And Adrien let's the last of his restraint fall away as he collapses into Luka's arms, transformation melting away as a sob shatters him.
Luka catches the pieces, holds them together as the grief and betrayal rock through him. They kneel on the bed, a gentle hum under his chest and a thumb pressing just behind his ear as Luka rocks him in his arms.
He doesn't speak. Adrien has no words for the gratitude that wells up in him at the comforting silence.
"Why didn't she tell me?" He whispers raggedy when the tears finally slow. His throat and chest ache, and his eyes feel chafed. There is an obvious wet patch on Luka's shoulder that he will probably feel embarrassed about later.
He scoffs, and accepts the tissue Luka gives him to wipe his face. "He asked her to. She thought she was protecting me."
"Oh." Luka breathes out, and it feels disappointed. "I'm sorry, Adrien."
"You didn't know." He says, pushing his head into Luka's chest like a needy cat.
"She came to talk to me. She asked for my Miraculous- I must have over reacted." Luka muses, running steady fingers through his hair. "She used second chance to take it back."
A purr vibrates his chest, and Luka gives a small sound, amusement. He finds he doesn't mind so much.
"What will you do?" Luka asks, softly, when his breathing has slowed and his eyes feel over heavy and his chest rumbles with steady purrs that make him feel the cracks in himself as much as they seem to fuse them.
"Can I stay the night?" He asks, mouth thick and slow around the words.
"Of course you can. You should not be flying back to Paris like this. We're lucky you didn't crash into the ocean." There is a little pressure on his head, as though Luka has pressed his face against his hair. "But I mean after that. What do you want the future to look like. Do you want everyone to know? Or do you want to keep it to yourself."
He tangles his fingers in Luka's shirt. "I want you to know."
Luka's breath huffs, and his face is very close to his hair because he feels it and he doesn't mind it. "Of course, silly cat. I'll know."
"That's as much as I want to decide right now."
"Ok, Adrien." The fingers resume their petting and he relaxes further at the lack of pressure and the steady warmth of Luka's heartbeat under his chest.
It's one of the worst days of his life, but he falls asleep feeling safe.
