Maki was damn worried for you - hearing from some source(the phone she slid in Gojo's purse) that you got injured on your solo mission. Going back and forth, pacing by the entrance. She, sure she cared for you. Not that she showed it - she didn't need you to turn weak from all her care so she was more tough on you then anything but it was tough love!
Her trail of thought paused when she heard the car approaching, her eyes darting over like a sick mother - her hand against her chin. The second you got out of that car. She swarmed it easily. Her hands grabbing you and checking every part of you to check for injuries without a word.
A way to start a conversation to someone who's been out for weeks. Squeezing her burned hand on your chin to look at her and squinting her eyes. "God, you couldn't have been back sooner?" Maki scolded, but it was mostly came from a place of relief.
Leaning over to kiss you, it wasn't long or a quick one just right. Maki didn't bring up the kiss, but it sure was the first time she visibly showed affection. "Don't be an idiot and worry me like that." Maki continued - pointing a finger at your face.
