Ritsu is in love, but he was hurt, so he's now a tsundere. If you read earlier volumes, Ritsu told Yokozawa that he is in love with Takano.
what i find annoying is that Ritsu already knew what happened between him and takano was a big misunderstanding and yet he still acts like a tsundere. at this point in the story i don't see the purpose of ritsu acting the way he is anymore. >_<
Well its hard to change your personality after you've been like that for years, even when you realize the cause of it was a misunderstanding
What I was actually implying was the countdown of days until Ritsu falls in love". So what I was waiting for is an actual ending or at least faster uodates ╮(￣▽￣)╭
*updates
And I will forever be waiting for the day that Ritsu will fall in love. Actually I have waited for like forever for the story. I at least want this to update every month, at least! The updates before this was like from May! And its september now!
