Ameiro Paradox
Ah, the rivals to lovers trope- definitely my favourite character trope. This is probably one of, if not, my favourite relationship between 2 MCs of all time. Their dynamic is so natural, comedic at times, but so realistic. The love they feel for each other never felt forced, and the romance that gradually built between the characters was well paced. If you like slice of life and a realistic, non-toxic relationship between 2 MCs, this manga is for you! This is the only BL manga I've reread 10+ times.
Twilight (Nishimoto)
The art is gorgeous. Super angsty, and a tad over-dramatic, but a beautiful sweet story nonetheless. This manga is romantic, cute, and a little sad, but it ends on an optimistic and wholesome note. Definitely underrated. If there's one thing I had a bit of an issue with it would be that the translation was not the best especially in the beginning; it was definitely difficult to understand at parts.
