So I also don’t know what it really means either (not just the word itself but actually having a honmei) - if I was overseas I could just pick different guys and it be whatever. From my fandom I’ve seen it’s like you stick to that one guy. Even if you’d rather pick someone else since in this case the band knows you (as a fan) and you kinda established a relationship with that dude so it’s just awkward af to pick someone else.
…very host boy ish 
Like when it came to 2-shots I wanted to get a pic with every dude and the merch guy just stopped me and questioned if that was what I really wanted to do (i.e. you cheater!)
hugs
I was very much in the same boat. If I was younger i’d be trying to chase my honmei but as I was already married to someone I idolized and when I realized what the difference a fantasy is between reality I was in too deep. So I bring up points like hey - they might not be financially well off which could be an issue if you’re way more financially stable than they are.
