What I learned from this manga:
1. Police stations in this manga are trash. Normally, they should've investigated it or at least look at the godamn security cameras!! You cant just say "Oh. Lets just say she ran away because she was broke." They should've first, looked at the security cameras, check who last met with her, ask her friends or close ppl if she gave any hints, or anything about her whereabouts, and then, maybe track her phone and do the other police stuff they're suppossed to do!??
2. Other ppl living in those apartments are litterally deaf and blind. Like hello?! Anyone there to report the the police about the loud banging sounds coming from upstairs, and the ppl who are shouting "GET OUT!!" or "DIE!!" Like, at least any passerby that isnt deaf!?
3. MC. Is. Reckless. And. Dumb. Like uh, why...would you tell then your secret!? To make you look cool?? Is that it?? And, hes soooo careless. What if he fails then ressurructs after 3 days and the girl is already in a brothel at the middle of nowhere!! Why didnt he take a screenshot of the picture the gangsters sent to the police to provide hin backup!? Gurl, if youre feeling like youre on top of the world or feeling like the btch of the btches, then DONT. This. Is. Not. The. Time. To. Be. A. Super. Hero. Wake. Up!!! This is reality!!
4. MC is high. Yep. Im sure. Hes DEFENITELY HIGH. Look how he saves a random girl who hes fell in love for 1st sight who he only met once in his life and just gave him ramen. Gurl, ramen aint worth your life. You aint your bad-ass daddy who can save 4 lives in a few mins.
