Canon on all years or no?

I just had an idea to think about.

Do you think the author will develop the relationship between Kiyotaka and Karuizawa during all 3 years of study? Or will someone else appear in this love line?

Me why something came thought about how, that kei and 50% will meet about year and break up. And then he started Dating Horikita. (If honestly I this at all not want, because kei the best girl, and Horikita I and so not very love) on fact I fear, that Kiyotaka will part with kei, for they the best couple in my life😢 In General, write what you think about it!

/I remember, that kei in really the early told that Kiyotaka will become the most important man for it in this school, but can this will be already in terms of friends?
