My main problem with this is that, while their tsundere couple antics are cute and all, their apparent mutual resignation to getting married to someone they're not sure they like, is just so tragic.
And in that context, if I take it more seriously than the romcom it's supposed to be, it's like—yeah, they like each other, but their relationship looks exhausting, and are they really good choices for each other or is it just nice that it's working out at all under the unfortunate circumstances... Presumably if this runs long enough that will be addressed, but in the meantime... x_x;
