Love Kodama's works. Unique author. Shitty people trying to make connections. This is so realistic. Good stuff.
This one is kinda mild by her standards , though.
It really isn't realistic, the thing that actually puts me off most of her works is how weird and unrealistic her characters usually act, although I guess I should give this one some credit as it is probably one of her more realistic ones. The gold digger turns out to be a poor girl desperate to get out of her situation and the "nice girl" friend turns out to be an entitled creep, this kinda thing is far more believable than some of her other stuff.
