Same author as the Hana to Usagi manga so art is kinda nice. I liked the chemistry between the couple. The blackmailing was kinda funny and enjoyable. Didn't like the part with the stupid ex and the almost non-con targeting with strangers prior to the endgame couple moments. I really liked the seme's personality. My favorite part was probably the epilogue (final chapter) where the uke doesn't act like a lover in public and insists on staying inside the whole time. And the seme is so considerate and lovely and eventually convinces him to finally accept he deserves happiness and they're finally both ready to publicly share their happiness and relationship.
