Now that the dust is settled, does one-sided love counts as romance? Funnily enough, the answer is maybe. Maybe because everyone confuses true love with romance, even my search engine.
Does this reading warrants a romance tag? I mean it is sweet, but the subject of child love is a tricky landmine to answer, so I'm gonna put it in "maybe yes" category. FBI-kun dont raid my house.
Tl;dr romance is subjective af instead follow your heart because thats what people in romance do.
