1. The first manga i think was a scary/horror manga where a guy who works in some company, asked to stay in a deep sea 5000?or maybe 10000 meter below it . He stay in some what like some tower bunker there and work there to do some research with over 100 people there. The thing is they lost contanct, all electricty shut down, it becomes dark and some weird dark creatures lurking around.

2. Second manga is about mystery, i am really sorry if this was kinda vague. Basically this manga is about finding a culprit err because he do something horrible i think. The MC was a high school student, i forgot if it was man or woman but i think the MC are 1 man and 1 woman who works together to find the mystery.

The culprit had inisial name "S" and they thought it was a person name. I still remember some scene about a wife and husband. Both of them are graduates from the high school the mc attend. The husband think he was "S" but in the end the wife say he was the "S". It was kinda left vague because in the end the wife just pretend to be "S", there was the real "S" and she did'nt know about it. And there was some scene where there's a high school girl, 2 of them talking, and suddenly one of them got hit by a car, the other one just err laugh and say she deserve it. This is kinda creepy and weird manga but i was curious wtf i just read in the past. Btw i don't know if the inisial was "S" , but i think they refer the culprit with inisial name, maybe it's not S maybe N, or W but i think it was S.

Many thanks

i do not know the 1st manga, but the 2nd is most likely bungaku shoujo
