MAH HEART!
Ugh, but seriously though, I hate this "I am in very gay love with you but I have to marry a man because of responsibilities and expectations" trope because yuri has such a bumpy track-records when it comes to happy endings. Normally, I would have just been able to tell myself that it'll be fine, it'll work out in the end, but because it's yuri, it can go either way because drama. I can seriously see the next chapter taking place after a friggin' time-skip where Mei has been married for years. Ugh!
