First of all, likely no. Top Media is a business company that only wants money. Top Media gave up on UP10TION and want that money money from Jinhyuk and Wooseok. However, UP10TION's 2020 comeback was expensive and they had a 18,000 increase in album sales (The Moment of Illusion - 34,842 to Light Up - 52,048)

in 2020, Jinhyuk and Wooseok are doing acting and were busy while UP10TION are doing nothing besides practicing in the dungeon (dance pratice room), having v-lives, uploading 3-4 fan contents before their comeback and preparing for their comeback. I'm assuming they were very busy between June to November in the dungeon. Sunyoul is also in Voice Trot (whatever u call it), idk much about it. The rest of the members didn't had any schedules besides their comeback.
And Jinhoo, well, from my POV (op POV), he only went on a hiatus cause of his girlfriend controversy or whatever and then went to the military. HOWEVER, he could've went on a hiatus due to health concerts probably but im not buying it. Along to add, Jinhoo had a mini mini fanmeet with a few fans in a cafe back in July. Since he has went to the military and his return date is near UP10TION's contract renewal, I guess it's safe to say he is leaving the group after his renewal (FROM THE OP POV).
Support UP10TION and buy their albums if you can!!
