Chapter 17
Spoiler:
Komari and Yukio skip school to go on a date together and tsun tsun hime finally takes the chance to tell her she loves her, it was about time. She also tells Komari about her family and the real reason why she had to return home.
They kiss in public for the first time but apparently that just isn't enough for Yukio-chan so they have to go back to the dorms and make love.
I guess this relationship has become something serious now.
And with that volume two is over.
