How should I put this? It's my first time to write a review so this MAY contain spoilers if I get carried away.
The second season is better and has more plot than the first in my opinion. What excited me about the second season is that it has plenty twists in every couples' story. I personally enjoyed Kisa and the book keeper's story. It has a strong impact and heavy drama which will probably lead fujoshis in tears. Although there also cliffhangers which will inevitably make you hate the anime but all in all the story is what delighted me the most about SH 2.
Sorry I had to give this a tad lower score than the others but hear me out first. My reason kinda sucks actually, it's because sometimes I get confused with the characters and I can't tell which is which! It's because some characters look almost the same. Same hair, same eyes, but, maybe it's just me. I don't know! I get confused a lot! Sorry but the art is just okay for me.
The soundtracks were cute although I didn't take a liking to them at first.
I gave this a perfect score simply because they were all perfect. Everyone of them, although I have my personal favorites, the other characters aren't to be overlooked. All of the pairings had this unbreakable and promising auras which will keep you wanting more of them. The antagonists were also good.
This anime is very interesting and commendable. Since this is the first yaoi I've watched, I don't have much to compare it with, but it will leave you both laughing and in tears... and peeved.
