Assuming the title colors thing is really a hint, I'm hoping 5 colors means 5 people, not 5 girls. It would've been perfect with just a throuple, 4 is already stretching it.
Especially because of the "serious" approach of this manga. It's not a harem with 10 women where you know from chapter one that 9 of them are there just for the trope and shenanigans (and broken hearts at the end).
Naoya is actually serious about a real relationship and making them happy.
Adding girls just means 1) more and more girls for him, which cheapens the premise. Or 2) automatic losers with broken hearts. I don't like either.
@spidersonbikes Ikr? It was such a refreshing manga with that premise, even if it was a wacko comedy. Sigh...
Just make it a 5P simply cause the girls are already there and broken hearts are bad, but stop adding girls Author-san T_T
