All of a sudden, flowers were no longer as pretty as they seem to Jihoon. Not when he was throwing them up.

the red string of fate bonding two souls together grant them the gift to communicate telepathically, but when one dies, it's like the telephone call being broken off. it's like calling out to an empty space but receiving no response but a deafening silence.

 Jihoon always thought that the waters were cold, later he realises that he was wrong.
