Yeah he was, a lil shocked at the sheer strength of his hug but, he still patted his back slightly, laughing as he couldn't help but somewhat enjoy his enthusiasm-
He smiled softly at him, as he slowly scooted himself down, so his arms would've been underneath his armpits and-yk, he was lifted in the air, spinning around with him slightly as he buried his face into his neck-
Buuut he didn't know, he just snuggled into him for a moment, before lowering him slightly. So now they would be semi-eye level....(able to bury face into mirio's chest TvT), smiling brightly-
"Heh, sorry, sorrysorrysorry, your just so gosh darn adorable I couldn't resist!"
