In fact, people always like to crowd out those who are more concerned by leaders than themselves. Maybe you think that you are "working hard" just to show your ability and work hard for your goals, and you don't want to show off, but in the eyes of colleagues, the leader really "values you" and it is human nature not to like a new person who is favored by the leader when he first comes. Don't blame them, and don't be unhappy about it. You and your colleague have a new comer. Don't be too enthusiastic in front of colleagues, and don't say what you have achieved. Try to keep a low profile. If you want to climb up and lead such a group of people in the future, you must win them over now; Even if you don't want to climb up, you should get on well with them if you want to work smoothly. The company is a team, only you can't do it. Get through this period first, as long as you have real skills, others will naturally take it. They don't like you now, but they don't know your weight yet.
