Honestly on the one hand I can understand Nori's fear. Sho has always been only with women so the fear of not actually being liked is human. But I can understand up to a certain point. I didn't like the bartender's speech.
"Make him like you so much so he won't go back (women)."
There is a constant denial of bisexuality, particularly in Japanese manga. It's normal to discover even in your thirties that you can also be attracted to another gender that isn't necessarily the opposite one to yours. Not for this Sho's feelings are less valid.
It's like being afraid to date someone who has had other partners before. It's normal for there to be afraid, but that doesn't mean that this person can't truly be in love with you.
Where to find a partner like Sho? (〜 ̄△ ̄)〜
