You make a good point there. If I were to rephrase it, it’s more like within the context of the story, it’s emotionally realistic. Kinda like if you’re watching Naruto or something, it would be uncharacteristic of him not to spend AT LEAST two episodes trying to talk-no-Justu his enemy out of fighting him. Within the context of the characters and the story, I think that none of their actions are coming out of left field or anything like that. Of course this manga is still melodramatic, more so than most Ive read, but within that context, nothing seems glaringly unrealistic, at least to me.
Going to you point about how friends are, it’s important to remember that these are two shy high school girls that have never had a single friend before (Konatsu purposefully keeps people at arms-length, and Koyuki was placed seen as unreachable by her peers) If things weren’t awkward, it would be weird.
Honestly, how you perceive the story just depends on how you perceive fictional relationships in general. If this same scenario were to occur in reality, I would not expect the two peoples interactions and emotions to be much different than in this story, thus this story seems realistic to me.
