Introduced should work here
I'm confused - I thought "했어요" indicates past tense? However, Duolingo didn't accept my answer of "The man introduced himself as Seojun".
That is now the standard answer (Sep. 2018).
introduced, past tense flagged 12/29
Is introduced incorrect? Or do I have to spell the name exactly?
Why not 자신 since it's used as the object here?
