While I couldn't quite tell from the title at first, the comment by the author at the beginning made me realize this story was going to be about psychology, which did live up to what they claim. In the story, readers will find psychological theories and the names of several psychologists and philosopher sprinkled in a practical and moderate way, which is a bonus point for me because I just like how some stories thoroughly incorporated the said elements into the plot rather than just use them as an opening excuse for the story to begin before jumping right into the lengthy drama/backstory/misunderstanding/sex/.... I wouldn't saythose elements related to psychology are being elaborated on an expert level that can satisfy intellectuals though. It is just enough to be respectful to the theme but not too much to become a cognitive turn-off.

Apart from that, the story is okay, I guess. It did what a yaoi is supposed to do - the art is easy on the eye, the characters are not overtly annoying, the resolution to the conflict is fair. But it isn't exactly profound or memorable either. Maybe it's because the characters do not really have anything super relatable for the readers to vent their issues?

In general, I think this manga is quite alright as a quick fix for entertainment.
