Sasuke - Naruto - Sakura.

"You were friends with that trio." You were invited to a party (you were 19-20 years old)... You were Sakura's sister, but compared to her, you were ugly and had blemishes on your face. Anyway, let's leave that aside. The four of you were drinking beer, too much, since you were having a drinking contest. You were already on your 5th beer and were drunk, Sasuke was on his 7th but wasn't as drunk, Naruto had 6 beers and was just as drunk as you, Sakura was on her 4th beer and was already about to burst.

Sakura: S-Sasuke-kun…how can you drink so many and not be so drunk?
She said, bowing to him. Sakura likes Sasuke, though she can't hide it.

Sasuke: I have more tolerance than you, that's all.
He said indifferently; that was always his personality.

Naruto: Look at me, Sakura-chan, I can still take way more than Sasuke!
He wanted to surprise her and took a longer drink, but almost all the beer spilled down his chin.
(YOU WERE SIMPLY WATCHING THE CONVERSATION WHILE DRINKING YOUR BEER WITH A MOCK SMILE)
