After all the trials and tribulations, we'll finally get that confession!
What trials and tribulations did the characters go through that's worth celebrating this momentous occassion you ask?
Why it's obviously Ichika randomly getting kissed by Kawase at the beginning of the series, then she started to struggle with her feelings.
What else you ask?
Well there's the fact that Ichika struggled with wondering whether Kawase actually liked her, since Kawase was kissing another girl. Isn't that something intense?
It's not...? You're saying that's nothing...?
How bout when Kawase's older sister, Rei, had entered the scene and talked with Ichika, and Rei got incredibly jealous! That was really something right?!
What do you mean that it's not?! It was really incredibly displayed and emotional! Oh you're not impressed?
Well don't be shock when you find out about how Rei gave Ichika a peck near her lips, in front of Kawase and the friend, which made them both jealous and upset, and set off the backstory arc that explained everything.
Explain the backstory in one sentence? Sure, Rei used to date the friend, but had to break up because Kawase liked Rei; so Kawase and friend started kissing each other.
And what happened next? Nothing. You're caught up now! Amazing right...? Wait...why are you walking away...? It's great right...?!
