The heroine is a little sad, a little mean, a little moody, a little gentle, a little complicated.
The male protagonist has many quirks, mysophobia, obsessive-compulsive disorder, sensitivity, and humor ╮(╯▽╰)╭
The third party who has no idea at all, the ex-girlfriend who committed suicide for the male protagonist, what is the ending of this love story that alternates between sadness and joy.
In the end, whoever speaks first does not live up to expectations.
