This manga is being adapted from the Japanese live-action GL drama of the same name, which those outside of Japan can watch on GagaOOLala! The platform also has a number of other great live-action GL shows (and LGBTQ+ shows in general) from all over the world, including Japan, Thailand, Korea, and more, making even a temporary subscription well worth it in my opinion. As far as Japanese ones go, I personally recommend the drama adaptation of Ayaka Is in Love with Hiroko, as well as a recent favorite of mine, Call Me By No Name (though this one is significantly darker in its subject matter).
i think this is backward? the drama was adapted from this manga, it just hasn't been translated before. anyway, i liked the show well enough, will keep an eye on this.
No, this manga is new. The drama was technically a spinoff of sorts based on a manga, but it wasn't this one. The original manga, just called Chaser Game (this one is supposed to be called Chaser Game W; it'll be fixed when our uploader is available to fix it), had a completely different story and cast of characters, and wasn't yuri. The Chaser Game W drama kept the game development studio setting of Chaser Game, but the plot and everything else were original, created specifically for the drama. Now, this manga is being adapted from that.
