. The story is about the MC transmigrating to different worlds without any memory. The lover of the Mc is also woth him everytime and he is also the one with the memory as he have the system with him. The ML is actually the one with the task to perform in every world and the Mc is just a typical side character with somehow OP setting but doesn't really affect the world. The Mc having no memory is actually because his physical body is damage and needs points for it to recover which is why he is also brought into the world with his ML. This story also has many arcs and one being like an apocalypse setting. in that setting its like the mc is great with animals and has wood powers (actually idk) and so he decided to live on the mountains. So after accomplishing the ML’s task at that world he then looks for MC and saw that mc is living peacefully. He found a big ass queen size bed and put it into the bedroom (without the permission of mc). one arc is where the MC is a craftsmen and does carpentry for a living. In that world the setting is like medieval ages (historical type). The Mc actually helped the ML in this world.
