Global examination
Read the world best engineer. I almost peed while laughing.
Not a single chapter where i wasn't laughing like a maniac
This and the list above are really great reads, can vouch.
Though worlds be engineer isn’t exactly what you’re looking for, it’s one of the best stories I’ve read in a while, competing for first.
Definitely should give it a try, on webtoon is the best since it’s free and you can support the author.
Not necessarily an idol story. I just really like this protagonist's personality. How he just does what he wants to do, not overly cold but not a pushover, doesn't sacrifice himself unnecessarily for others but also has a sense of justice and helps others within his capacity. The side characters are also well written and unique in their own way, and they are all so cute mannn. I just want a story with like a similar atmosphere, where you can be happy supporting the mc and seeing how his every little action impacts others around the him in unexpected ways. Little plot twists like how the mc actually helped the side character tremendously by trading away the frozen food balls which he cannot eat really warms my heart in a way yk.
