Wonderful Life Forever

It's been eight years since we've been dating, and it's almost been a year since we've been living together. I, a fledgling illustrator, and Takumi-san, a motley man, know each other's spirits and have a perfect physical compatibility. There were times when things didn't go well, but now we were supposed to be in love, but recently Takumi-san has been acting strangely. No, he was a cold person from before, but he wasn't this callous. Could this possibly be a dull period!? A younger, lazy dog x cool elite glasses tsundere dull BL.
