Let me share a reading report of BEASTARS, a manga series by Paru Itagaki.

I’dve been interested in BEASTARS for years because I really liked “Monster” by YOASOBI which is the opening song of the anime, and. Then there came thea chance for me to read it.

私も「モンスター」という曲が好きです。

This sounds better as two sentences. It should also be present tense because you're still interested in Beastars.

FThe first 4four volumes of BEASTARS were available for free as a sample at a Kindle store during this nyear's New yYear’s holidays.

We usually write out the numbers 1-10.

I began to binge-read as soon as I found out about them out and never stopped reading until the end.

It had been a long time since the last time I had read such a good manga.

I’ve been thinking about love on and off in my life, and found it as one of my life works to think about how I can love both others and myself.

They struggle to be in a good relationship as we humans struggle to live together with various others people who are so different from each other.

Even if one can’t understand the other, they still have possibilities to live peacefully together by trying to understand, each other and not forcing anyone to share the same ideas, habits, and religion, etc.

Isn’Wouldn't it be great if different people could live together sharing something valuable like happiness?

Since you're hypothesizing in this sentence, the tense is subjunctive.

SI strongly recommend it.

Let me share a reading reportmy thoughts ofn BEASTARS, a manga series by Paru Itagaki.

“share a report” sounds like you’re presenting information that someone else wrote.

I’d been interested in BEASTARS for years because I really liked “Monster” by YOASOBI, which is the opening song of the anime, and there came the(it just so happened that) I finally got a chance to read it.

“got a chance to” is a common expression. “just so happened that” can be added for emphasis if you want.

I began to binge-read them as soon as I found them/found out and never stopped until the end.

“to find out” can be used when you learn new information, but you can’t really put it with “them.” It almost makes it sound like you’re unveiling that “them” committed a crime or something in that case. See #2: https://idioms.thefreedictionary.com/found+them+out

Even if one can’t understand the other, they can still have possibilities to live together by trying to understand,, through not forcing each other to share the same ideas, habits, and religion etc.

“have the possibility to” is fine, but feels a bit unnatural to me. I reworded the second clause to avoid repeating “understand.”

IsWouldn’t it be great if different people could live together and sharinge something valuable like happiness?

ThaIt is a very good manga.
