Why do they still use this trope?

The production is good, the acting is good and it's a very good cast, fit for the roles. The story is good the first two episodes, as it centers on how their relationship evolves and how they have had feelings for each other, even though they never actually said a word about it. The last two are about unnecessary dramas that don't really add to the story, such as all the fight about the river or the reappearance of the ex-girlfriend and subsequent illness. At the end, all I could think was "So, all this for that stupid bury your gays trope ending?"
