Adachi betrayed our expectations again - it seems like Harada, in fact, is guilty of breaking Touma's finger - but only one of it! Why did he do that? I think that both Touma and Harada realised that they were too honest to keep a complete lie going, so they decided to make that lie a partial truth - and that worked like magic. And judging by Otomi's reaction to a similar situation that happened with Anna-chan, she actually doesn't mind being protected by her brother, lol.
The next chapter will be released on December 12. Stay tuned!
