MySql. How to combine several columns in cursor?

I will be very grateful for any help. My situation.. I have a table with students (I write only main columns for this question):

| Id | Lastname | Firstname |
_____________________________
| 1  | Smith    | John      |
| 2  | Williams | Robert    |
| 3  | Wilson   | David     |
...

A table with works:

| Id  | Name    |
_________________
| 1   | Work1   |
| 2   | Work2   |
... 

A table where write who did this work (number of students who can do the same work can be any)

| Id | WorkId | StudentId |
___________________________
| 1  | 1      | 1         |
| 2  | 1      | 2         |
| 3  | 2      | 1         |
| 4  | 2      | 2         |
| 5  | 2      | 3         |
...

And I need to make a table in procedure (with using cursor) like this:

| WorkName     | Students                           |
_____________________________________________________
| Work1        | (Smith J., Williams R.)            |
| Work2        | (Smith J., Williams R., Wilson D.) |
...

I don't understand completely how to use cursor in this case. My code:

DELIMITER //
CREATE PROCEDURE Report()
BEGIN    
DECLARE students VARCHAR(200);  
DECLARE id_s INT;
  
DECLARE done INT DEFAULT FALSE;

DECLARE get_cur CURSOR FOR 
SELECT Id, CONCAT(Lastname, ' ', LEFT(Firstname,1), '. ') FROM students;

DECLARE CONTINUE HANDLER FOR NOT FOUND SET done = TRUE;

open get_cur;
read_loop: LOOP

FETCH get_cur INTO id_s, students;  

IF done THEN
LEAVE read_loop;
END IF;

SELECT w.Name, students
 FROM Work w
JOIN WorkStudent ws ON w.Id=ws.WorkId
JOIN Students s ON s.Id = ws.StudentId 
WHERE s.Id=id_s;

END LOOP;

CLOSE get_cur;  

END //
DELIMITER ;
