Well. I guess CJ Michalski must be good or at least popular, because I see her name on the cover of comic magazines all the time. I hope this isn't an example of her best work, though, because it's bad to the point of being funny, almost, like a parody of the genre. I somehow doubt it's intended as a parody, though.
The whole thing is rushed, which makes the story uncomfortable. The characters are like puppets, acting out the expected parts of a BL story (the kind where the sex is shown), or at least the highlights, but without anything to let the reader feel that they're real people. I've seen this kind of plot be done in one or two chapters of about thirty pages each where the characters are sympathetic and more-or-less dynamic, but here it's three chapters of cardboard cut-outs. They're marionettes dancing to the expected BL pattern. Thus, you can sort of understand why I'd almost suspect this to be parodic of the genre. Except since it probably isn't (there isn't anything satirical or funny or even exaggerated, except for the pacing and lack of personality), it's just uncomfortable and forgettable.
I like time travel stories, but this one isn't worth qualifying as time travel. Furthermore, the translation by Datenshi Blue could really use a good English-speaking editor. It's fairly obvious that the translators are not completely fluent in English (or else aren't cognizant of how to make a translation sound like natural speech), and though this can usually be overlooked in manga with good stories, it doesn't help Michalski's manga at all. It might even make things worse.
