I love how this manga is really thinking deep about what it means to love or fall in love. Especially when a character like Sensei has never been in love. That brings up the question of how do we know we've fallen in love? For someone who has never experienced love, its hard to pin point if its actual love or maybe just lust/like.
I'm glad Sensei is making these questions because he could easily be a character that says "well he loves me...maybe I love him too?" and then just accepts it and they live happily ever after.
But once Sensei falls for the other guy, he'll connect the dots and his mind will explode! And I can't wait to see that!
This last chapter really connected the dots and now we understand why Sensei was questioning love and why he felt that no one could love him. I mean if the parents that loved you abandoned you, of course you would think other people that love you would do the same. So to protect himself from getting hurt and hurting others he just refused to love anyone. It's easier that way because you avoid going though that pain again.
But I'm so glad that Shishio was able to make Sensei feel like he shouldn't worry about that because Shishio ain't going anywhere!
Ugh I just love this manga so much. The story is soooo good and this is gonna be in my favorite yaoi manga list xD
