'Warning: mild gore scene.'
[Pupa: Ding! An original hidden plot has been triggered! The Ugly Love!]
[Wait, a hidden plot?! Does this mean Long Shen has a secret or something dangerous in him?]
[Pupa: No, the original hidden plot is a bit different. This is like a memory from the original Ragemeter world, a fragment of what you did to Long Shen until he became mentally deranged.]
Pupa downloaded a bunch of data and poured it inside Yunyu's head.
The first thing that Yunyu saw was this exact scene with Long Shen kissed him for the first time and begged for his forgiveness. In this original Ragemeter world, nothing changed much between them.
Long Shen bullied and verbally abused Yunyu, found out that Yunyu had been in love with him for so long, despite his horrible treatment. And with the Guilt Tripping no Jutsu, Long Shen's heart was finally moved.
