Awesome!This would be normal for a sugar arrangement. For regular dating, not so much. Women like this are, while not commonplace, definitely not entirely unusual in Japan. I've run into a handful over the years.
Hearkens back to the 90s when Tokyo girls were rumoured to have a string of boyfriends....
Honmei-kun (term from horse racing meaning favourite) their main guy
Kiipu-kun (Japlish for keep, as in keep in reserve) the backup to honmei-kun
Mitsugu-kun (tribute) a guy who's kept around for presents or money
Ashi-kun (literally foot) the guy with a car who could take them places
Benri-kun (useful) the guy who knew how to fix or sort things - also sometimes called Koodo-kun (cable guy) if he's kept around for tech support.
Basically, she was trying to set you up as Mitsugu-kun.
i will talk to my Japan teacher about those words, at my next school session, what mean kun?
