Though Japanese BLs (and J-Dramas in general) tend to be on the shorter end watch-time wise, this drama is a great example as to why that is. You don't need that much time or endless drama and build-up to tell a good story.

Kimi no Koto Dake Mite Itai managed to deliver something that felt real. It managed to deliver a story that you could easily see in your daily life, yet still keep your attention. It has lovable characters all around (especially the teacher side couple), and delivers a sense of nostalgia and optimism that hits at all the right spots in the brain.

Give it a try. Unless you desire in-your-face romance, this drama should not disappoint.
