This series started with a pretty decent premise, but the last two chapters have slipped into "Yaoi hands" territory with a quickness. My prediction: The brothers start to fuck for, I dunno, some reason, I guess.
@dokidoki Emiri is for sure gay, but the point of this chapter at least is that she doesn't actually know this for herself. See: the tea choice bits, and her repeating her mother's thoughts on marriage. She doesn't even realize that options outside of marrying some dude are even available to...

Go back and read those pages again, and you'll notice that the only actual FACE you get to see is Miwa. The other girl is either shown from the back, or has speech bubbles over her face. It sure SEEMS like it's Saeko, but the author definitely left the 'one-shot' ending open.
