Its really sad to see Uda mustering all her lil courage to confess and get immediately misunderstood, but well, right now wouldnt really be the best timing for that and could instead make things very awkward when Riri is still grieving her heartbreak and also worried sick to mend her friendship. At least made Riri for once really look at Uda in a new light.
In a way this whole development was way more complicated then ive expected, like, ive hoped Riri would start to look at Uda before things got this far. But i guess it make it seem like the series is far from over which is a plus, considering theres nothing more really happening with the mcs at this point.
