I know you with 〜のこと知ってる

In a close-up, the spiky-haired boy narrows his eyes. In the next panel, he leans on his desk with a grin while Chii turns around in the seat in front of him, puzzled.

It’s Chii’s first day of middle school. During self-introductions, the boy sitting behind her keeps staring at her, then asks whether they’ve met before. Chii teases him by asking if he’s hitting on her, and he insists he’s just a little curious.

男(おとこ)の子(こ):
「……やっぱり、」
“...Yeah, I'm sure of it.”
「オレ お前(まえ)のこと知(し)ってるわ。」
“I know you.”
ちー:
「え?」
“Huh?”

Key Points

1お前(まえ)のこと知(し)ってる
  • のこと after お前(まえ) makes Chii the person he knows. The full form is お前(まえ)のことを知(し)っている.
  • 知(し)っている works with or without のこと. Without it, it leans toward knowing someone personally. With のこと, it can lean toward knowing things about them. Here the boy just means he’s sure he knows who she is.
2知(し)ってる, not 知(し)る
  • “Know” is 知(し)っている, with ている for the state of knowing. 知(し)ってる drops the い. The negative is 知(し)らない, without ている.
3やっぱり and わ
  • やっぱり means “just as I thought”. He had wondered whether they’d met, and now he’s decided they have.
  • わ at the end of a statement is a light, casual assertion. Male speakers use it this way too.
4お前(まえ)
  • お前(まえ) is a blunt “you”, common among boys. It sounds forward when used with a girl he’s just met.

Vocabulary

(As expected)

やっぱり shows that something turned out as the speaker thought, or that the speaker is coming back to an earlier choice: “after all”.

(I)

オレ is a katakana spelling of おれ, a casual, masculine word for “I”. It is also written 俺(おれ).

(You)

お前(まえ) is a casual, rough word for “you”. Men often use it toward people of equal or lower standing.

(Thing)

こと is an abstract thing, matter, or fact, as opposed to a physical object. It also turns a verb phrase into a noun, as in 見たことがある. It is also written 事(こと).

(To know)

知(し)る means to learn or come to know a fact or person. In the form 知っている, it describes already knowing.
