To Lead Astray
To Perplex
transitive verb, godan verb
The word 迷う means "to go astray" but this word is to lead astray. You are doing the astraying to someone or something else. You know this because the other person was (わす) just fine until you came along to lead them astray.
The reading comes from 迷う, so use that so you aren't lead astray too.
