These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Future Lovers
Strangled by the Red String: Kento decides after what can't be more than a week of getting to know Akira that he's willing to give up his longtime dream of a wife and kids to be with him for the rest of his life. It's not as bad as in many other yaoi manga, however, and the development of their relationship beyond the "getting together" part (especially in the second volume) helps loosen the red string considerably.
It was actually two weeks but the point still stands.
