The reason that things feel off to a lot of people with this 'couple' is the idol dynamic. The manager's description in this chapter that they 'are in different worlds' disgusts me, and I bet others who read this feel the same. Getsuyobi no Tawawa started as something the author did on Mondays to cheer people up with cute girls who have giant honka-badonka-donkers. The manga has established itself and its universe as a place where love is simple and easy, so when reading this storyline, it comes across as way too dramatic in a negative way. I think that if this storyline were a totally separate manga it wouldn't bother people as much, but in the tawawa story, this is almost dark in comparison to the other couples' stories.
Well that's my take. Let me know what you think.
