... Oso's rooster is still alive.
Ichi has a dream where Oso promises to back off and leave Kara to him. When he wakes up, Oso is "using" Kara. Ichi brings the stopwatch and they have that competition from the beginning. Ichi kills Oso's rooster because he's mad at Oso for still messing with Kara. He has lunch with Kara, they have sex and confess that they care for each other. Oso comes back later and asks after his rooster because it's obviously disappeared in the ramen...











I was expecting Tetsu-nii to adopt Touma, since he's the older one. Like, if there can't be a marriage, at least they can share the name that way.
But it was surprisingly good for a brother/brother story.
