So I heard in this fandom, it’s ok to ask for other girl’s help if you cannot cheer up your own sweetheart. Looking at the way the other girl changed your sweetheart’s world, dried up his rain and making him happy, Everyone knows that their bond is completely platonic. However, it’s a lie if you didn’t feel envious of their platonic relationship… But what can you do, you can’t blame them. It’s not like they are having an affair. It just that the other girl is your sweetheart’s ray of light and you are not. So you, being the kind person you always be, shall accept this fact and keep silent in the background while your beloved finding comfort in his BFF’s presence.
