can someone tell me the summary of this manhwa please

Mc is poor working part time and dreams of being a novelist someday. He can also see people's past lives when his lips touch someone else's. Ml is rich and takes a liking to mc. Seems like ml is gonna teach mc about things (relationships) so mc can be more knowledgeable about the world as he writes his novels. Thats all they got so far. It's kinda cringy and cliche but nothing overtly problematic yet
