I read it q 2hile ago and only a few chapters, but I remember that mc was asked by a loli if he wanted to be isekaid, he didn't agree, was Isekaid anyway, ended up in some weird forest and ended up duper op there. He trained against golems or smth and was super angry at the loli and was like "I'll beat the $#!t out of that brat if I find her" that's all I remember of it
Nidome Jinsei, maybe? I remembered that there's a loli goddess forcing him to transmigrate, but I don't think Renya (MC) went & bash a golem in early chapters
