I think an asexual route for him would be good, but it should start already in the beginning. You can tell he is manipulating you or trying to. Here I would like an option to kiss his cheek and say "I care for you, but you don't feel the same."
And then from then on he will still confess to falling in love with you later, and you can go all the way to the end as asexual or demi-sexual.
It is unfortunately clear that we are a group of representation that has seriously been neglected as every romance is so heavy in sex.
Even romances like Halsin's that starts as a slow burn, turns into a kink fest.
I wish they had been more sensitive to people who are not driven by sex, but intimate emotional connection.
