People saying this is using misunderstandings to drive the plot. But unless I'm missing something, aside from the senpai planting the idea of scams recently being a bit outta nowhere to do this, it makes sense for Sunao to be wary?
Like some random girl you don't know shows up, asks for directions and then knows way too much about your personal Life. That's something to be wary of and likely to be either a stalker or someone trying to scam you. Lemon is being a bit too stubborn tho, like he legit told her what he thinks that Raika is a scammer and tho she doesn't know Raika she's jumping through hoops to make herself think they've been secretly dating? Like I like the 4 protags so far but Lemon legit the most annoying somehow cuz she's acting a bit too possessive over someone she fumbled like that in the past. Like if there are a lot of misunderstandings tbh they're coming from Lemon not saying anything about that or telling Sunao she likes him or Sunao not telling her he has someone he likes atm as well.
I appreciate Suzuka tho. He handled that well. Like he was also a bit skeptical but when she started being sus he realized Sunao may be right. I kinda want the story to go back to him working out his emotions regarding whether he liked Lemon herself or Sunao personality in Lemon. (Like we know the answer but he should work that out haha)
