所以 in Context

I like the course and have recommended it to a few of my friends, but for a while now I feel I should provide a bit of honest feedback on how I've been feeling about it lately. This can be deleted after it's read and I hope it's taken as a constructive criticism.
I'm struggling with the sizes of the sentences. Getting over 100 of them to review every morning, them being as big as
男人又说：“ 其实这三颗种子是死的，它们开不出花。大儿子和二儿子为了公司，选择换了种子来骗我。但是小儿子选择了诚实，所以他没有花
uses up all the time I have to learn Chinese during the day and it's becoming a bit demotivating. I don't think they should be given as options to add for the flashcards. These sentences are both hard to read and also very hard to shadow when they take 16 seconds or more. And by the time we get to the 所以 part, I'm just too tired to understand what I've read. The bigger context confuses me more than helps me. Like why we're talking about seeds and stuff. I know, this is part of a bigger story, but when I'm just trying to understand what 所以 means, it becomes a huge diversion. Surrounding words with such big sentences personally is having a bit of a counter effect on me and pushing me away from the course to the extent I'm really considering whether I should renew my subscription or just stop it here. Even though we know most of the characters here, I don't see this piece as something we could call "comprehensible input" as we don't have the other parts of the story yet, so I feel it could be given to us broken down in more smaller chunks.
And yes, I know we can choose to remove some of the sentences from the reviews, but still, doing this can give us a feeling we are skipping material, so I'd prefer not to get them appearing on Traverse at all, or ideally broken down into smaller chunks. Counting the periods here, this could have become at least six or more difference sentences rather than this huge one, which we'll get to read anyways when we get to the whole story, but then it would be only once rather as a reappearing flashcard.
That's it from me. Thank you for reading and I hope this helps somehow.

re 花儿们
I thought 们 was only used for people? or if not, what class of things?

So we have been getting these stories sentence by sentence and I just unlocked the sentence : 男人又说：“ 其实这三颗种子是死的，它们开不出花。大儿子和二儿子为了公司，选择换了种子来骗我。但是小儿子选择了诚实，所以他没有花。Mind BLOWN! I just yelled out loud "OMG the seeds were DEAD the WHOLE TIME!"
I didn't see that coming! A total drama, so much tea to unlock this morning ;) Also... super clever of the father.
LOL, these stories are fun to unlock this way!
