Doesn’t it make sense? The prince was injured in the past, so now everyone looks down upon him. He meets the guide, who is able to heal him, but actually has hidden motives. The guide planted a love gu in him, and which will cause him and the prince to fall in love with each other over time while also poisoning them. He wants to incite the prince to destroy the royal family or kill the king, perhaps both. The childhood friend is in on this cause, but for reasons not revealed yet, decided to try assassinating the prince and is caught. The guide begs on his behalf, which is seen as a betrayal by the prince.
I'm not really sure which story I wrote this comment under, as it doesn't show up for me/I can't see it, so I can't really go and fact-check, but from what I remember, if it's the story I think it is, I wrote this when there were only a few chapters, no clue how the story has progressed since, but it made no sense at the time - mc tells ml to guide him - ml guides him - mc tells him not to guide him anymore and threatens him - ml guides him - mc threatens him - mc tells him to guide him (or something similar to this, I remember that the mc kept changing his tune), all this pulling back and forth is a little annoying, and I've been similarly annoyed by other chinese manhuas, not all, but most.
Cliches, expected unexpected plot twists, things happening conveniently to push the plot forward and tie the pair together, no communication between the pair, just random shi happening, and mcs changing their mind at the drop of a hat not speaking exactly about this one, cuz I dropped it right after that weird dynamic, but chinese manhuas are often really chaotic - one chapter they're enemies, the next they get reincarnated, the next they are lovers, too much things happening at once, too fast with no room for digestion, some are slow-burn, some have such fast pacing they could be a one-shot but there's no balance, no in-between.
If it's not that story the nvm, I don't remember which one it is

Why are the plots in chinese manhuas so weird I love the art but the story makes close to zero sense
