@c sadly one room ta remains top of the top for me. you can try heesu from class 2. its tooth rotting sweet and so adorable. the spooky love tale of gongchan (i dont really rmbr this one but i know i liked it). 'who can define popularity' is good as well. its similar to one room ta in the way that it explores its characters past their interest for each other. hope this helps!
