Damn. I didn't expect such an unanimous reception for Yugami. It's already number one in this site. Looks like MangaDex really has a thing for slice of life, and I'm not complaining. This place is something else.
@scarletcrow we should consider the facts involving this free fries LOL. One of the girls said that the pizza delivery was surprisingly fast. It's not really surprising since the delivery guy was Yugami.
Or, it could be just the girls being clumsy with time. But then again, we're talking about Yugami here, that Yugami.
Or, it could also be it was just Kuzumi who was watching baseball. The ball slipped by and the batter either failed or succeed in his run. Therefore the remark, "already? that was fast" LOL. Or she simply said it because it was the end of the match then it's time for the girls to get the plates LOL. The tv screen only showed a guy succeeded in his run though.
Things in the previous paragraph could be a decoy judging from the context & sequence of conversation bubbles in that panel. Or, it's simply lost of context because of translations.
Perhaps Chihiro was the one who ordered the pizza & her name was written on the order/receipt. It's highly probable since they gathered at her place after all.
Lastly, a pizza restaurant or a pizzeria usually gave out free pizza or coupons for your next order, or simply gave out your current order for free as a compensation.
This is where you need context in this chapter and informations from the previous & the next chapters to fully understand what really happened.
All things considered, adorable isn't it? This manga made you do deductions like Sherlock Holmes, but unlike Mr. Holmes with all his murder cases, we have adorable & cutesy stuffs.
As for me, I already have one solid interpretation of the free fries. But, damn, the writer & editor really did their job with the panels & bubbles arrangements.
Just reread the manga for the sake of understanding all the hints & allusions. This manga totally deserves the rating.
