Everyone is definitely looking into this short form Twitter comic about a tsundere office lady way too deeply.
Maybe my translation and wording is lacking, but she's not playing mind games with him. She just can't be honest with herself and open up to the guy. First chapter, she just wants him to say "I like you" because she's probably not used to hearing it often. Second chapter, she tries to be cheeky and a little flirtatious with the "I'm not that easy, mister" line and he takes it as
himself coming on too strong. Third chapter and he blindsides her with the "I come to the roof to see you" line and she tells him to stay away because she's blushing furiously.
It's just a basic tsundere rom-com, you turbodorks.
