Ah. So he has no interest in the marriage nor does the girl. Both did the marriage just for the respect of their grandfather/master. The girl also said they have different fates because she found hes a trash while she is a genius since she reached 4th dan of eagle in such an early age so she probs wants to just not pay attention to this entire marriage bussiness and just wants to do it for show. The boy wants the excalibur sword.
Now even tho i didnt really like how the girl straight up went from his home and was really uninterested, i still think that once she realizes how strong he really is, she will come to like him.
Anyways, i really want him to show his strength more and not let others call him a trash because that's just annoying plus it will make others realize faster just how strong he is which will be fun.
Anyways the art is also amazing and im digging this series though i wonder just what level our MC is. Actually i also wonder how hes able to hide martial aura, maybe he really doesnt have martial aura/arts and in reality practices something else, maybe sword arts and sword aura. Or maybe his level is too high to actually be seen or maybe since his level is high, he is able to hide his aura. Anyways story is interesting. So the girl in the last panel seems to be righteous but is dumb. She probably will think the other guy was poisoned by our MC and will try to stand up for him. She's probably strong.
