I loved this when I read it with my sister. It's not as creepy as I thought it would be and doesn't border on pedophilia or power dynamic like other mangas with large age-gap. This feels more real and the characters emotions feels more genuine and reasonable. The ML struggling with his life and his siblings after the death of their parents and finding solace in the work of the MC (she's a writer).
The little bro was cute too. I would honestly support him and MC too if that ship had any chance to sail. He caught feelings for her when they were children, after his parent's death he crouched down crying infront of their graves in the rain and the MC quietly sat by his side holding an umbrella sheltering him from the rain. No words had to be spoken and that panel warmed my heart.
