yellow dragon's manga / #Back in time(2)

i don't understand why people hating it. it's good and has happy ending? man just isekai'ed by truck kun and back to the time he met his senpai. his old senpai cannot bring himself to tell him he love him and marry another girl his parents arranged him to. now that all the misunderstood been clear they can be together and the plot fixed. it's literally so cute why the rating so looooow!!!!

not rlly suit my taste. sub acting all confusing the top but glad top still likes him
