Sunao ni Narenakute (2010)

It's too about a (new) group of friends, where each and one of them struggle to find love and happiness. It also has a similar sub-plot later on and a minor jump in time.

Both of them about the young people who are looking for their way in life.Sunao ni Narenakute is a little darker and confusing but both of them give a hope about life in the end.

I recommend this both drama because , Male lead and Female lead
try to solve problem
In one drama explosion and another student murder/suicide

Ichihara works at a magazine where he is being blackmailed into sexual favours by his chief editor. Park, on Twitter, takes on the persona of a doctor, when he is actually working at a company that sells medical equipment to disinterested doctors, and at the same time, trying to take care of his younger sister.
This is a story about the blossoming friendship of five young people who were brought together by Twitter and their journey to finding honesty with each other and with themselves
