This is how I imagine Luna trying to justify her “сasual” encounters with other guys to Naoto, all just to avoid “ruining” her relationship with him. I’m so fucking fed up with the whole "Luna" and “Luna-nee” thing (it’s not like she has schizophrenia).
Anyone else in Naoto’s position would’ve dumped her by now. Between the rumors, the memories of her kissing/going out with multiple guys, her selfish decision to keep using a dating app when feelings were already involved, and her contradictory mindset of “I swore I wouldn’t hide anything from him again because he hated me for it once, but I still have to keep hiding things,” Luna comes across as an unnecessarily complicated character who constantly contradicts herself.
She makes you think that, for your own well-being and mental health, the best thing you can do is stay away from people like her.
Unfortunately, since Naoto is a typical Japanese MC, he’ll probably have to put up with her until the very end and accept her for who she is, whether she’s promiscuous or not, even when he has an absolute catch like the girl with the sawtooth teeth right there.
The only thing I’m sure of is that the moment Suga reveals that Luna has slept with another man (even if it happened just once and was when she was dating her only ex-boyfriend), the fandom will go straight for her throat like a pack of hyenas.
