I think this is a decent anime - despite receiving some not-as-high ratings by previous viewers. The art is really really good for sure, so you wont be disappointed on that front.
The plot is not bad - I dont know about other viewers, but I could predict the major plot twist much in advance. You will really feel the bromance when you watch this, but it's not shounen-ai or yaoi or anything close. Just nice, brotherly/family love.
You'll probably appreciate the MC's personality. As the middle sibling, he has some inferiority complex towards his talented older brother, and he wants to get stronger so his brothers can rely on him.
Anyways, it's worth watching. I smiled at the end, and felt like it was a good use of my time.
