Ryouma's glad to be looking up when they come around the corner at the end of the hallway, as usual standing close enough together so that when they took a particularly well-timed step their shoulders brushed together.

Takatora was dressed in his usual work clothes, which of course meant he looked impeccable, though he looked impeccable all the time. Kouta was laughing at first, which made him as good as glow, and he looked comfortable which was much more important to Ryouma than any preconevied notions of fashion or proper etiquette.

He grinned, because Kouta's reaction is truly excellent. He actually stumbles to a stop, Takatora has to grab his arm to keep him from falling over. Takatora looks surprised, himself. Precisely the reaction Ryouma was aiming for, just by being in the hall waiting for them. The suit was just a... a bonus.

He moves away from the lab door and towards them instead, and manages to catch sight of the tell-tale blush creeping across Kouta's cheeks.

“Oh, shut up.” He said with good nature. “You look amazing.” He reached for Kouta's hand, and gave him a little bow before leaning in to kiss his cheek. “Happy birthday.”
