I was kind of expecting (with the summary (implied he hadnt seen her in years) a situation where it was like they were adults or something (the volume cover atm makes the girl it shows look like an adult, so...), maybe some actual drama.
What I got was (self-inserting author?) another herbivore MC in high school with zero testosterone in a harem that goes nowhere for 1000 chapters number 28792789234879.
If you want a story that isn't a copypasta herbivore/beta MC having zero spine to reciprocate interest of multiple bishoujous that genuinely like him, don't bother. So tiresome how many works get dozens of chapters while I've seen several great stories get axed/rushed the past few years.
