flowerss's manga / #dungeon(1)

MC was on a great dungeon with over 1,000 volunteers. which only 4 survived and 2 committed suicide after MC went in hiding after the great dungeon and was (still is) completing his friends final wishes like knotting a hand made sweater and so on the reason his friends probably gave those final wishes was probably for MC not to kill himself as after the great dungeon and doing all those hobbies, he still was very traumatized later in the story, MC exposed to everyone that he was the famous hunter that survived the great dungeon after trying so hard not to be found out BTW, ML knew/figured who he was first
