Overall, my bet for the continuation of the plot is that another, but completely critical, misundrestanding will occur, when they finally lose control of their feelings, there will be a terrible fight with personal attacks, someone (seme?) will finally trample the pride of the other (uke?), and they will part ways with mutual resentments to the ceiling and beyond. And then they will learn the truth about each other third-hand. Although... Overall, it's uke who seems like a softie, who will cave to the bad character of the little brat as easily as possible because he's older and smarter (because he's a lovesick pushover).
