Prince Sum Mo is eagerly waiting for the arrival of his friend, he has a big group of friends but after meeting with Chiyou, he has started meeting them less and less.
There are various reasons but the main reason is that Chiyou genuinely cares and makes decisions that are in his (Sun Mo's) profit, whereas his other friends make decisions that is mostly based on their profit.
This is expected as they all are from a noble family and all of them have an eye on the royal treasury of Sun Kingdom, but Sun Mo is not so stupid and he is rarely allowed to give in to their words.
Thus, Sun Mo himself started cutting his toes with his friends slowly slowly.
