Okay, first, let me immaturely giggle at the symbolism and innuendo of the lock and key again. The opening image really really makes this shit hilarious.
“IT WENT IN!!!”
Also, it’s funny how the lock belongs to Raku, and the key to Chitoge. lolol oh man…
And because Chitoge was too forceful… it fucking broke!! WAT!? DAMMIT! And here I thought we finally would get confirmation… with the chapter titled ‘Confirmation’ and all…
All signs were pointing to Chitoge, and I thought this chapter would confirm it. And it did… sorta. Her father told Raku how he met Chitoge ten years ago when he came to visit Japan. This pretty much sets it in stone, right?
Time for the rage, the father also mentioned Raku and Chitoge played with “her”:
GOD FUCK DAMMIT!!
WHY WOULD YOU MAKE THIS TURN OF EVENTS!? HE MET BOTH OF THEM!? HE FUCKING PROMISED BOTH OF THEM!?
BOTH OF THEM ARE THE GIRL!?
AAAAAAAAAAAAAAHHHHHHHHHHHHHHHH
This is just… fucking dumb. Why the hell would you do this!? Trying to make it more complicated? Trying to prolong the manga?
*sigh* Oh well, let’s see where it goes from here.
Open Your Mind 
uhh! raku make a harem when he was a little brat!
