So, this girl Hiiragi says she has the complete collection of books at her home, but she actually doesn't. She was caught red-handed buying them.  
The next day she appears at school with a suitcase filled to the brim, with underwear visibly spilling out. 
She's adamant she HAS to go to Aritsuki-kun's house. 
They only just met and blud got a clingy girl obsessed with him. 
This chapter made me laugh like an idiot. Thank you very much for the TL!!
