mature and refined as in locking lover up out of obsession, lying to lover out of fear, and no real communication between the couple at all (even after like 5 ch of abuse)??? tbh, I rlly liked the plot at first, esp with all the magic and action, but everything that's been happening recently just really turned me off. on the verge of dropping ╮( ̄▽ ̄)╭
Also u are being a bit too dramatic
1)locked up? Not really the tone is playful and the uke is kinda playing along.
2)lying and no communication, uhh u read the same thing as me? He is a assassin obviously he has to lie, also no communication? They are both Hella busy and relationship is not their main priority, it's the same for both party that's what makes it mature.
Rant over.

This has official reached to 5 start level for me, man I love how mature and refined this couple is, wish there were a hundred chapters for me to binge.
