Pluuuus this is a perfect combination of smexy and fluff (⌒▽⌒)
I don't see how that indicated it improved? To me it sounded like it got worse.
It's kind of like the reality of relationship in real life. You can't have butterflies in your stomach forever, same as that your ways for keeping your partner by your side and working through your relationship will change. It was explained that at first, they were keeping each other by their performance in bed, teasing each other etc. It was shown that it may be a bit desperate way, it still works (rmb that by working your way through a relationship, as much as you have to make your partner feel contented and happy, you should be too). As much as they look cute when teasing each other, let us not forget that they were confirming each other too, meaning that there was an anxiety that both of them are afraid that the other will leave, or that as time goes by, their sex would get boring or smth. But finally, years later, they no longer need to strategize ways for the thrill of the chase, nor depend on each other with a heart quickening need (aka the fun/teasing part of sex) both of them had a nice, lukewarm relationship. They no longer have the anxiety nor the continuous of strategizing a hot, steamy sex, because both of them are finally contented with each other.
...or that's how I interpreted it mehehe tho I think they still have hot sex every now and then ლ(´ڡ`ლ) (without the overthinking that one might leave the other or smth)
I was surprised, in a good way. At first I wasn't sucked in (not too much fond on smutty yaoi lol), but the last line stucked in my kokoro dangit. When the narration mentioned that "Their relationship changed after 5 years", I was wondering if it was for the better or the worse, and when I saw seme-kun in drag, I figured out maybe they became friends? And when I saw megane-kun lolol I was so assured that their relationship degraded. But the last line im the narrative that said "No longer do we depend on each other with a heart-quickening need, or strategize for the thrill of cause." I WAS SOOOO ECSTATIC AND SHOCKED WHEN THEIR RELATIONSHIP IMPROVED!!!!! ┗( T﹏T )┛
