Sadly I've read both of them already
Seinen - Sekine-kun's love. HANDS DOWN. I've never cheered up for a manga character's love life so badly than him.
shounen - nisekoi (this is harem tho but i am into harem) i actually really like this, the concept of "sawaze in love" key-thing is romantic.
Shounen/Seinen manga with best love story?
