So I'm like a hardcore Given fan and I still liked this adaptation for 3 reasons:
1. The song that replaced fuyu no hanashi was so fitting for the drama! i understand why people don't want another song, but fuyu no hanashi makes sense for the anime because the story was told like the manga. the drama took a different approach to the story, so the new song made more sense and fit it better. neither song is better or worse than the other, they just make sense for their adaptions. the ost in general was really nice.
2. The acting was great for almost everyone (i have a thing against mafuyu's actor's acting because it's just too monotone for me, but some people enjoyed so i won't say nun about it) but i LOVED uenoyama's actor! he was so expressive and i could feel the emotions through screen. i really liked the rest of the cast, you could feel their energy and it was just enjoyable to watch because of them. also, yuki and hiirage's actors were PHENOMENAL like my heart broke even more from watching the added romance scenes between yuki and mafuyu and hiirage's pain.
3. boi support good bl adaptations so we can get more! i want a ten count or hitorijime my hero adaptation jdkshfsdjkhdj
