Yep, that definitely had a way worst impact for Tsukasa than intended. Well, the idea was stupid to begin with since they never had just a regular friends relationship before the letter so this attitude could change things for worst. But Yoriko didnt take Tsukasa feelings into account at all and it was definitely heartbreaking. But im curious to how Tsukasa will act next since she does like Yoriko and should be more than anything, utterly confused, but a part of me surely hopes she pays in full to Yoriko for being so mean.
Just thinking the letter author might be someone knew it only makes me think this is gonna take a while still.
Also, tho is the plot, Yoriko creepyness always gets me by surprise (licking the can), giving a feelings Tsukasa is dodging a bullet, is so conflicting lol
