Thanks for the chapter!
Has he ever talked about those two being his fiances before or pretending to be his fiances? Seems out of the blue but might have missed it before. Poor MC, no matter which flower he picks he'll get pricked by her thorns along with those of the other. Question is, will the other people in the party be smart enough to take a great distance from the two or be arrogant and stupid enough to close in to a few feet to spectate? Would be funny if some drunk idiot with delusions of grandeur mocked the MC and said two beautiful ladies should be with a great man like himself before being ko'ed by a simultaneous death stare and mocking denial from the two. Personally would be fine if he had a relationship with all three if could avoid most of the political problems with the 2nd princess like being on call or restricted from travelling and such. After all, with how magic and eqiupment has leveled down, lack of information trading hence few doctors who rarely share discoveries with each other, and high mortality rates from monster attacks polygamy to ensure continuation and increase members of the bloodline would be common sense. Wouldn't be surprised if king had a few other wives and concubines for that although have only heard about the 1st and 2nd princesses and king but not about their mother or other siblings like younger sisters or older/younger brothers. Granted king might have been romantic type and only loved the queen but need to know more about them to be sure.
