I became a first-class guide thanks to my childhood friends
MC is a lvl D-class guide and has friends who are A-class espers one day, he got really drunk with his friends and his friends (MLS) took him home but when they opened the door to his house, MC fell and pissed his pants afterwards, he wakes up with marks (sex marks) all over with his 2 friends beside him on his bed after that incident, he went to work like usual but he then suddenly got notified that he was a S-class guide
My 2nd Chance on Taming an Obsessed Esper
MC is an ordinary person until a S class esper came and kissed him then MC regained his last memories from his past life ML already knows his last life
Tesoro of the Guide
MC is a researcher (forgot name) that helps check up the espers and give them medical care before it's serious, also they check if their wavelength is good MC is that kind of doctor and a f rank esper, he meets up with this guy who's an A rank guide there's also this other guy that saved MC 10 years ago which is the reason whyy he started to choose this profession
