Dear my beloved bro, Manjiro.
I know that heartbreak is the saddest thing in romance and yeah... I totally understand your feelings, because I've had my heart broken too but do you know that 'the Sun' is always alone up there and doesn't need anyone no no maybe one day the sun needs a companion but
the sun knows that it is not easy to reach because you're special it does not matter!
he/she is just confused because
his/her heart can't choose, I'm sure that you can forget it slowly and
you will get the best of the best in this world and everyone deserves to be happy with their choice as well as you. so, I hope u can forget about it and be happy with people who love you more, inc me. I love you
Jiro.
