The ML isn’t as straightforward as the one here so he can be a bit cold but the FL is funny and kinda similar to the FL here. It’s from the same author as Lovely Complex
Wait, sorry! Here’s the first one - https://www.mangago.me/read-manga/dame_na_watashi_ni_koishite_kudasai/
The link in the previous comment is the sequel

So so so refreshing!! I relate so much to the female lead!! Never wanting to grow up, being an otaku helps survive reality, a lil gullible, caring... i wish we had more relatable FLs like this. Sometimes, i just want a story of a "loser" and not a girlboss. What ML said ab FL being who you truly are and him 'loving' her comforts me.
