If you enjoy a MC that is continually trying to power up his friends and himself through various means. Then this might be worth reading. If you enjoy a MC that is continually trying to think one step ahead of his enemies for the sake of keeping those around him safe. Then this might be a the manga for you. If you enjoy a story that involves more than just the MC being really powerful then this might be something worth reading. If you're looking for a lot of romance with a harem then this isn't the story for you. There isn't much of thatat all.
The title itself is a bit misleading. It is more along the lines of "Because I want to live my life as a loner I will make sure the lives of those around me are peaceful".

Characters
There are quite a few characters in this story. In the beginning we have the MC and 5 different groups of classmates. As the story progresses more people get added to the list for an even livelier bunch.

Story
The world itself acts a bit like a MMO. Killing monsters gives exp when levels you up and makes you stronger. Monsters can drop loot or materials to sell at towns for currency. Being the resourceful guy Haruka is, he quickly becomes accustomed to how the world works and what limitations he has to work through. He even sets up a home at a nearby cave after clearing out the monsters within. He is quite ready to live his life as a happy loner. If only he didn't run into his classmates shortly after.
Once he solves some of their issues,( and after they camp out at his luxurious cave for a bit), he decides to help them reach the nearest town and that's where the story really begins.
From then on it's mainly dungeon crawling, comedic shenanigans, Haruka trying to be one step ahead of future enemies with his plans of keeping everyone near safe.

Why I recommend this?
The MC is great. He seems so carefree in everything he does, (this constantly throws off friend and foe alike), but he's always striving to find ways to improve not only himself but also his team. The way the story handles his relationship with his classmates is pretty well done I think. They recognize he's a special individual, yet strive to keep up with him and reprimand him if he tries too hard to go alone as a loner. There is just no malice at all and that is what seems to make this story so lighthearted even at times when things get serious.
The chapters are relatively short at around 13 pages each and there really isn't much downtime content wise so it's there is always something going on. The beginning might feel a bit slow but it picks up quickly. Haruka may be a loner but he certainly doesn't get to play as one.
