I used to be very introverted like you, but if I don’t become introverted now, it will have a bad influence and dim your future. You must give up the development of introverted and cheerful character

Introversion will make your friends gradually alienate you, so you must be cheerful. You can join a club that is like a hug group (little reporters). If there is no topic, you can just talk about something (such as asking about family, study, star chasing, hobbies etc.) Make more friends and you will slowly become cheerful
