Tsukishima didn't plan to embarrass Kuroo with that comment, only tease him a bit. He likes Kuroo's messy hair, but that's a secret. "It suits you," he says with twitch of lips as he hands over the bag.

"Happy birthday. That's the gift in the bag." He hopes it's something that Kuroo will find funny/acceptable as gift. If not then he'll have to come up with something while he's here. He's trying to cover up the nervousness by looking idly around the train station, fingers entwined in front of him. He wants to congratulate Kuroo his birthday in different way too and train station is not good place for it.
