Yeah !!! Tht rgt !!! Arghhhhh
but in Asian culture not to bother anyone is number one priority. it all comes to Asian conspect of face, so basicily Ichi-san don't want to lose his face in front of Narita (at the same time keeping her face by not putting in any awkward place, which would make her feel uncomfortable). ofc, they should talk it through but I think that we a lot of times forget about different mentalities people have. I also feel like he should figure it out by himself. I understand that he's in toxic relationship and it makes it much harder to deal with this particular situation but making two girls fight with each other is so low that I would hate this solution. so I also hope they'll gonna talk about this at one point and Narita will support him, not solving all of his problems for him!
This is why communication is a vital thing in a relationship. If only Ichi-san would tell Narita that the other girl is bothering her, maybe they could figure something out. Maybe Narita could talk to the other girl, a little bit of bitch fight if you will. All of them are anxious, hurt and confused, if only they could talk it out. (〜￣△￣)〜
