Yet again a cliche,
where the MC doesn't know his own true worth,
gets his childhood friend taken,
becomes a great/popular guy after getting out of his comfort zone,
gets a harem even though he is dense,
the childhood friend loses everything when the lord decides to throw her away for someone better or sells her to slavery,
comes begging MC for help bcoz nowhere to go or live,
MC accepts as returning favor to the one who raised him,
either does a one time favor and sends her away or keeps her as friend,
manga gets axed. THE END.
The above is just a prediction, I don't real novels.
