The first and second volume have VASTLY different tone.
The first volume is your typical Omegaverse romance--it even starts with your usual noncon--and all things considered, it's very typical of most BLs. The seme is gruff and possessive, the uke is horny but shy.
But the second volume takes a HARD turn into domestic fluff. I don't mind that at all--the turn DOES improve the story and fleshes out the characters more, but even I find the evolution a bit jarring.
Still, all things aside, it's a good story. The art is clean, the smut is lewd, the fluff is sweet and soft. I really enjoyed it.
