Reading this feels like a dream. As if author had their long-term memory removed and they forget everything that happened more than 10 chapters ago. Classic case of a manhwa/manhua not being planned out and just picking a focus at random once they reach the end of the short script.
Spends tens of chapters on HS then just leaves it, okay. Spends so much time on cooking then abandons it. Goes on a trip which leads to MC falling for a girl he literally just saw and pursuing tradintional medicine because he met an old guy (which was like the 7th old guy he met) in like 30 seconds flat. Then it's back to cooking and acting. The original love interest is forgotten and then it's about the daughter of the cook, who then leaves once he meets the trip girl. In the middle of all of this he recieves a letter from a love interest we haven't even seen before talking about their first kiss, like what. Why?
The worst part is, I could actually see it working. It's a great premise. MC going around taking odd jobs and gigs, meeting and helping people, visiting places, learning and teaching things... you know, getting "experiences" for a "book of experience" that he can trade to get to know other experiences contained in the book. Less about an OP MC and more about making connections and people helping others because they were helped.
But right now it's not that. Author has a place they want to end up and they do not care how much sense it makes to get there and worst of all they pad it out too. It doesn't feel organic. He meets a granny with a brain tumour so he goes to uni to become a traditional "doctor" except after that, 5 of like 50 chapters actually have him do anything related to the university. MC's randomly introduced by an old guy he knows to another old guy, then he spends sooooo much time to get to the point that his museum or something ain't popular withe the youths. Then immediately MC meets a superstar that he can cook some kimchi for in exchange for a commercial of said museum. Contrived as fuck.
