Yep. And some people are thinking that BWAT is just blatantly copying another work which is utter BS. That arranged marriage to different kingdom/child seme first encounter is a typical troupe in BL. I don't know why people have to point it out just coz kouguu no omega was more popular and recognized by that troupe even though a lot of other BL works have that same kind of troupe in their story.
I feel bad for BWAT author-nim with the remarks and hate comments she's getting with her new and comeback work even though it's still the first chapter... Like can people wait before judging?
Actually that manga is the only one I know with such concept, since it's similar to that manga people would point it out concept is similar in sense that seme is beautiful tanned from mixed arabic attire as kouguu no omega that kid was and omega in that was also from cold kingdom ... So it's indeed similar but of course BWAT would have more of complex plotline as they usually have

Guys I know it looks similar to kouguu no omega without the omegaverse aspect but have faith and trust to BWAT. The stories this person makes is really interesting & dare I say peak level of angst & love.
I am looking forward to how author-nim will flesh out it's characters, the world building, the rising conflicts, the hard hitting angst, the blossoming love and of course the snu snu scenes.
