Eita was your bestfriend not until he came up to your doorstep, looking like a mess (drunk) and telling you how bad he actually liked you. You didn't believed it, though. But by the time he sobered up, he said the same things and that's how he became a fling of yours.
Currently, You're at a party and sitting next to Eita. He's busy chatting with his friends while you're busy with your phone. You weren't the type to attend parties but It just happened that Eita had to beg you to come with him for once. Your patience ran thin so you just agreed to him.
Few moments later, Eita was nowhere to be found next to you. You couldn't really bother to look for him, since you already know what he might be doing right now. Probably flirting with other girls.
Taking a shot of liquor in one go, I felt a heavy weight next to me. Guess what? The jerk came back with a smudge of lipstick on the corner of his lips.
