Are you being jelly, Ferid? Looks to me that he is (wouldn’t be the first time, he has those mean childish jealousy episodes every now and then, especially in the novels) because no one loves him and no one will go for him to the lengths that Yuu is ready to go to help Guren. But well, this is what reigning with fear and cruelty naturally results in, everyone on that bus is ready to throw Ferid under it if only they were strong enough to. And well, that’s what makes Ferid such a fine villain.
As always, now, to wait for the next month’s chapter to find out what shocks are in store next.
