Honkai Simulator, I'm really not Seele!

After traveling to the world of Honkai Impact 3, Lin Xi was bound to a "Xi'er Simulator".
As long as the host successfully conquers or rewrites the fate of plot characters in the simulations of various worlds under the guise of "Xi'er'er", he or she will be able to obtain talent rewards related to the plot characters.
However, if the simulation is rated too low, not only will the host be locked out of the relevant script, but the host will also be forcibly bound to some "weird" talents after the simulation.
As the simulation progresses, one beautiful girl after another falls in love with the gentle arms of Lin Xi, who plays the role of "Xi'er'er".
then.
Ailixia: Xier, when will our wedding be put on the agenda? ?~
Mebius: Let's do something fun, cute little Seele?
Big/Little/Beng Tieya: Seele! Bronya finally found you! Let's get married! *3
Kiana: Seele is really gentle and cute!
Lin Xi, who was wearing Xier's vest to gain benefits in the simulation, did not realize that he had completely become Xier's shape.
Lin Xi: You are looking for Xier, what does this have to do with me, Lin Xi?
Until the object in the simulation, and even the real owner in the quantum sea, came to force a marriage...
Lin Xi: I’m numb!
