Of course, I have to admit the fact that I got some money that I have prepared for my tuition studying abroadsaved up that I can use for my tuition.

Yesterday was a rainy day, and I drove my e-bike throughout half the city.

I met a lot of my colleagues when I was riding.

work colleagues or? 同学 doesnt really have an english equivalent, u can say like classmates or associates

An interesting thing that happened was that I got lost in the shopping mall.

Since I am almost due onlate for my delivery time, I am kind of anxious.

You can imagine it asImagine if you were stuck in a strange place, you cwouldn't have gotten out the righcorrect exit right away.

What a pitySigh.

可怜 doesnt have an equivalenmt in english rlly

You know, the lunch time.

?

Finally, I remembered a signalthat there was an electronics shop, and because of that, I arrived at my destination on time.

whats a signal shop? you mean like a shop for getting a phone?

Of course, I have to admit I've got some money that I have[quite(?)] some money prepared for my tuition studying abroad.

I might be being picky, but I think something sounds a bit unnatural here. It sounds like you are actively getting some money when I think you mean you have it prepared.

Also, "Of course, I have to admit" sounds a bit confusing to me and I'm not sure what it means in this context. Admitting something is usually about something embarrassing, OR it sounds like you're suggesting the money that you saved here is a pretty big amount (which you might need to give more context to make it clear that this is what you mean, and it's a little strange to use "Of course" for having to admit something).

You know, the lunch time.

Alternatively, you can write "You know: lunch time."
