[Taichi threw a party for him. Taichi had gone through so much effort just for him. Hikaru knows Taichi had probably never done catering before if he was going to compare him to Haruhi who's really his only other commoner example but he knows Taichi. These aren't things he cares about. He's simpler than that.

This explains why Kaoru had been missing sometimes and why it felt like he was hiding something. He's talking to him about that later because how dare Kaoru know all about this while Hikaru was agonizing over Taichi. But that doesn't matter.

He reaches to grab Taichi and hug him tightly. Taichi can't see his face but the hug should say enough.]

Youre so...so...! I can't even think up the right word for you right now! Everybody's freaking out about going home and you just...you throw me a party! [And nobody's ever gone through this kind of effort for him. Maybe he's had parties that were planned a year in advance but those had had ulterior motives. It had never been to just make him happy. Not like this.]
