Regrets

Corrected version by Gemini 

One of my biggest regrets is missing out on my second-language course during my third semester. My friend and I had planned to take Italian together, but I fell asleep and missed the sign-up deadline. My mistake also affected my friend. We were unable take the course together

We agreed to try again the following semester, but the course was already full. So, we ended up going two semesters without Italian. Despite the missed opportunity, we still managed to enjoy ourselves during that time.

During our last holiday, we successfully signed up for the Italian course. Now, as we're finally taking the class, we realize it might delay our graduation. But I suppose that's just part of the learning experience.
