If you liked the Watashi ga Motenai no wa Dou Kangaetemo Omaera ga Warui! anime, the Anime-Planet community thinks you'd like:
Ken Kubo is a normal man with a normal job who is besotted in a normal way with a female friend. But life turns distinctly abnormal when he meets an otaku, Tanaka, and is indoctrinated into the obscure world of anime, model guns, and garage kits. As Kubo finds himself shunned by those he cares about, he becomes only more determined to evolve into the ultimate being - the Otakuking! But Kubo is not the only one coming to terms with society. While he strives to mould the world into a perfect haven for people like him, otaku all across Japan are laying bare their strange, lonely lives for the first time… and it’s not a pretty sight.
There is an awkward moment in both of these titles that it really brings home the uncomfortableness of Otaku, and socially inept people.
Watmote really delves into it with situations, while Otaku no video does it with some interviews with real life shut-ins.
Both shows will not always leave you feeling uplifted. But in the end it can feel like someone is making a personal note to others who have these social roadblocks.
After being turned down by his unrequited crush, Hachiman Hikigaya is determined to live out the rest of his high school life single and socially tuned out to avoid the folly of youth. But Hachiman's resolve is lacking compared to his guidance counselor, a woman determined to change the boy's ways. So, much to his dismay, Hachiman is soon forced to reach out to those around him by joining a club dedicated to serving others. Alongside the cold, but beautiful club president Yukino, eager Yui, and other new friends, Hachiman will try to stomach his new volunteer work and survive his ultimate fear: being involved in a typical high school romantic comedy.
Both shows feature a main protagonist who's a bit of a social outcast, and one that many viewers can easily relate to in one way or another due to the situations each find themselves in, and how each deals with said situations.
The differences are that Watamote focuses almost exclusively on the comedy, and while Yahari certainly has plenty of humour, it places most of it's emphasis on the drama side of things. Overall it's also a more uplifting show than Watamote is, not that that's saying much.
