Ore to Omae no Stalker Boushihou
I had an ex who became my stalker after i tried breaking up with him multiple times in the course of 15 weeks. AND IT WAS HELLA ANNOYING AND FRUSTRATING! he did the same thing where he would always know my location and who i'm with, he would follow me everywhere i go. then he would keep calling me with different numbers and he also followed me on every sns i was on using different accounts and kept on messaging me and even my friends(he would ask them about me) i had to tell everyone my situation so they would stop answering his questions about me. in the end, i had a restraining order put on him so he would stop bothering me. so yea, yamada is actually a lot milder and sweeter compared to my ex. but all in all, these types of stories should stay in fiction since stalking is not good and is very stressful for the victim. worse cases are even much more difficult to deal with, if you are experiencing these kinds of situation then please do reach out for help.
