There was no clear connection between manga recommendations and the original work because manga were usually adapted from the original work, but recommendations could be made according to specific preferences and needs. If you like an author's work, you can recommend other works by that author. If you like a certain genre, you can recommend a similar manga. If there is a clear theme or plot requirement, you can also recommend comics related to the theme or plot. When recommending comics, one could refer to one's personal preferences, interests, needs, and reasons for recommendation.
