I don't agree, his whole reason for not wanting to date her is he doesn't think she'll take the relationship seriously.
But how is Shishou supposed to know something like this? You're saying he's stupid for not agreeing to date her because the author of his story said he would be able to trust her? There's no indication in the story itself that she would give a shit at all.
Volume 1 sold so poorly they had to make a bonus chapter begging people to buy it or they'd get the axe; since then male cupids were introduced and it's been all straight couples. I don't think it's a quota, more like an editor tapping the author on the shoulder and telling them to pivot away...
