。
She looked into my eyes.
Literal
She [topic-は] my eyes [object-を] looked-at.
Compact and direct. 目を見る ('look into someone's eyes') is the standard collocation for direct eye contact. In Japanese culture, sustained eye contact is far less of a default than in many Western settings — looking into someone's eyes carries notable weight, often signaling earnestness, sincerity, or emotional intensity. The simple past makes this a single committed act of contact, not an ongoing gaze.
