I Pretend to Be a Sweet Girl Every Night, and the Campus F4 Beg Me for Affection

[1vN + harem rivalry + female disguises herself as a man + taming dogs + everyone has a System] Zhu Yu transmigrated into the role of a villainess who coveted the good looks of her prestigious school’s F4.

The aloof, ascetic Pei, the student council president, visits her dreams every night to beg her to cosplay with him. The radiant, sunny top-tier star forces himself to share her sensations while she plays, then bursts into tears like a puppy. “Sis, is making me lie to you 999 times part of your KPI?” The gentle, elegant genius painter eavesdrops on her thoughts, then smiles as he warns the other three: “My girlfriend is adorable. If you find out, you’re done for!” And that terrifying, gloomy, obsessive yandere is actually trying to turn back time…
