Why are people reading romance if they don't want drama? It can go only 3 ways:
1. Love triangle and its iterations possibly branching into harem, drama, or tragedy. (Orange Road, Gotobu no Hanayome, anything written by Seo Koji)
2. One on one relationship that barely goes anywhere for 100+ chapters but the wholesomeness keeps you reading. ( Boku Yaba, Go home Akutsu-san, Kubo-san, Bijin Onna Joushi Takizawa-san)
3. The relationship starts early and the series is about their relationship. (Tsurezure children, Ase to Sekken, WotaKoi)
There is no other possibility for a title that is just about romance. What. The. Hell. Did. You. Expect?
