I think he would have waited for some more time if he can not buy the real one. I don’t know his sources but going by his nature he would surely gift a real one only for his beloved wife..
How can he buy that big ruby with 55000 salary yaar! He has to sell himself for that 😜. Or he could have kept CN under mortgage to buy this gift 🤪. He could totally do that after all he is neck deep in love with his baiko. If that is the case then let kaku take the pendant after all she has to repay the debt on CN 😂
