Loss in Investment

A trades in Forex and his friend, R, decided to invest Rs 25 Lakh. Terms were that A would pay Rs 21,250 every day to his R But if in case there is a loss, R would allow 1 year to A to return the principal amount of Rs 25L. No agreements were signed. Initially after receiving Rs 5,94,325 within a few months, A went into loss and informed R in Oct 2024. Now R said he wanted his initial investment of Rs 25L back immediately. As per the verbal agreement, A asked for 1 year. But R refused and wanted back the money immediately. At that time A's wife was undergoing IVF and R took advantage of that situation blackmailed A into signing documents stating that he would return the funds by November 24. This agreement was signed in October 24. R refused to give A copy of the said agreement despite several requests. A's wife has been trying for a mortgage loan to return R's investment. R is well aware of that and A has been giving him constant updates about the loan process. Yet R and his family have been constantly calling A and threatening him. Infact today R came to A's society with his family and few boys and created a scene in front of all the society people and went around telling everyone that A has taken his money on loan and not returning it, which is completely false. Now A's lawyer has suggested to do a GD. What will be the consequences if A does a GD against R?
