 If you liked Steins;Gate |  ...then you might like Seishun Buta Yarou wa Yumemiru Shoujo no Yume wo Minai |
Both Shows deal with Time Travel and Despair. One is a movie and one is a series thereby the latter making it longer to reveal the secrets behind time travel. A story about second chances.

Since Steins;Gate is way more known, i'll just say that I definetly felt a Steins;Gate vibe in Seishun Buta Yarou wa Yumemiru Shoujo no Yume wo Minai Movie, the first season of Buta Yarou must be watched before the movie ^^ If you haven't seen Steins;Gate, just go watch it
Plot is related to time and there is romance involved in both.

-Both of them share a similar back-drop - Going to different timelines to change or alter the protagonist's relative present -Some scenes will leave you in denial, which is a good thing when watching a show of this sort -If you enjoyed the premise of either, you'll enjoy the other show too :)

It has a very similar plot line with a main character having to use time travel to save the people he cares about. Similar themes of grief and dealing with loss are touched on. Keep in mind this is a sequel and requires watching the original series.

Both of these anime have the main character wondering to themselves which of two people they must save. They know that even if they manage to save one person, it's painful to lose the other, and they must find some way to save both of them. This can include making decisions that have big risks, losing memories, and possibly not meeting someone in the first place. They will do whatever it takes to make sure that everyone is happy in the end.

Without spoiling steins gate, both shows have a main character while fully being aware of the weird things that have been happening around them, they both have a female figure that supports them throughout the series, and especially in the movie they both delve into the theme of time travel o alter a tragic future...
