There are many reasons. For example, because Han Geng was in poor health, the company still asked him to make a lot of announcements, so he quit. There are also family reasons, treatment and other things, as well as the relationship between members, so the combination is so scattered. However, shinhwa is the longest-lived group in Korea, and no member has quit or changed in fifteen years. You can pay attention to the following ~ ~

On May 1, 23, SM and Myth whose contract expired could not reach a fair agreement acceptable to both parties. Myth refused to renew the contract with SM, and the contract expired on the 8th, ending the five-year contract with SM completely. In June of the same year, Myth switched to GOOD ENTERTAINMENT to start a new acting career. Note that Myth's contract with SM Company expired, and there was no contract dispute. In addition to the collective job-hopping of six people, he also successfully took over the right to use the name Myth. Note that after the contract with SM was completely ended, Eric, the captain, studied law and negotiated with SM company alone in order to find a way to maintain activities under the name Myth. After all the six members spent their savings together and paid huge sums of money, Only then did I get the right to use the name "Myth", the right to use the stage name of members, the fan organization "Myth Creation (the official organization of mythical fans started by SM Company)" and the right to use songs (the right to use is different from copyright), but the trademark right of Myth was sold to Open world by SM. Being the first and only example of an idol group that successfully broke away from SM and can be completely preserved was just a collective departure, which shocked the whole Korean wave circle at that time. No group has ever given up solo flight because it wants to keep the name of the group and keep going with the members. Only the myth has not been dissolved, and each has politely declined the personal signing invitation from the new and old entertainment companies. In particular, ERIC, the captain, refused the opportunity that other companies offered four times more signing fees than their members, and joined hands with five other people to sign up for GOOD Entertainment, trying his best to keep the resounding name of shinhwa (11113 tvN TAXI live talk show Dane Kim Kim Dong-wan). Myth signed a contract with a new company, and had the right to some independent activities. ERIC, JUNJIN, Dane Kim Kim Dong-wan and ANDY filmed one after another, and the S group of Li Minyu and Shin Hyesung released an album, and everyone started colorful personal activities. Myth has created an activity mode in which SOLO activities and combination activities of members cross each other and members compete healthily, which has opened up a win-win route for later idol groups to develop together with individuals.
