They are modest and kind in appearance, and it is easy to make friends, but it is difficult to become their bosom friends. Unless you are better than him, smarter than him, or you have an obvious advantage in his interest, let him find it inadvertently, otherwise don't deliberately show it to him. Even if he praises you, he should be low-key and modest, don't show pride and hide your obvious shortcomings, otherwise it will be difficult for him to really appreciate you and treat you with heart.
