Aw man, why is the artist always capable of drawing better looking woman? This is just my opinion btw, beauty is subjective. It just seems like with every manga I read, there is a side character that I think looks way better than the FL, and I'm always wondering, "why couldn't the FL look as good as this?"
I guess my preferences don't align with most mangaka and readers, since what is popular and "FMC material" isn't really my thing. I don't like tsunderes or flat-chested girls for example, I prefer sexy ones (not saying the things I listed can't be sexy), but the FL is almost never sexy in my eyes. In this particular instance, I think the beauty mark of the ex makes her look better to me, and I don't like the snaggle teeth of the FL.
Also, I know this is all sounding super shallow, let me just iterate I am solely stating my preferences based on looks, if it was personality I would 100% choose the FL. Personality is more important to me, but why not have the best of both worlds, top appearance and top personality? Well, I know the answer to that, it's because to most readers the FL does have the top appearance, my tastes are sadly rare and I wish it wasn't that way.
Okay well rant over, these are just thoughts I have had for a while and decided to type out for once. If you want to insult me for writing so much (which normally happens) I just don't understand why, no one if forcing you to read my comment, you can just move on, we should all be kinder to each other.
Edit: Okay now looking back at the chapters, I have changed my opinion, I think the FL probably looks better than the ex. She has bigger breasts which I like, I think the beauty marks of the ex just clouded my judgement, and I am referring to the chin and eye ones, I don't like the ones on the forehead. My point still stands though, it just doesn't apply to this manga. I know its pathetic I wrote this long rant and it doesn't even apply to the manga I am writing it under, but I am used to being pathetic
