This is such a beautiful relationship! Here are two people who profess love to each other and can discuss anything even though they're not really a couple.  The platonic  relationship of these persons is something that's rare yet very precious  and I liked that in this film there was no imminent conflict that  would eventually break that beautiful relationship that they have.  A special bond like this between two persons is indeed unique  and in this film, it was kept alive  and burning  despite the changes in their lives.  Well thought-of plot,  commendable acting performances and definitely a must-watch!
