Wonderful Life: Forever

Takumi and Tomohiro have been together for eight years, and they've been living together for almost a year now. Tomohiro is a fledgling illustrator, and Takumi is a much more popular artist. There have been times when things haven't gone so well, but their love for each other has never wavered... But lately, there's something wrong with Takumi. He's always been curt, but he's never been this cold. Is this a sign of fatigue??
