Male MC who transmigrated into the body of a young boy in the slums. The boss of his place brings back a sack, only to be assassinated while MC is gone. MC deals with the assassin and finds a pink/purple haired girl around his age, who turns out to be the kidnapped princess. MC was captured and tortured as he was suspected for kidnapping the princess, but is released when said princess vouches for him. His reward for saving her? He goes to the magic academy. Later is framed (forgot what for) and has to leave the academy/country. Last I remember reading he helped a young beastkin girl who also transmigrated but was a slave assassin, brought her over to the beastkin/demihuman country, and met the country’s council + a dryad. Also, MC has some sort of ‘dreams’ where he meets/talks with a woman; it later turns out that the woman is a high ranking spirit that lays dormant in MC.
