this!! the ml and mc didn't end up each other (at least in season 1 and idk abt season 2 bc i havent read it yet) and for me it was angsty and very realistic. ml literally groveling on his knees for mc to comeback and it is really great for an mc to stand mercilessly his decision! definitely a art and a good read!
One of my favorite ever:

The third ending *
Anyone who knows a story about unrequited love? It's like when they keep chasing the other person and then when they got tired, the other lead will chase them after. PLEASE I NEVER GET TIRED OF THIS TROPE. ALWAYS MADE ME CRY ಥ_ಥ
