Nisekoi 225 - About Raku
I’m just going to say this because I am really passionate about this: Raku REALLY cares about Chitoge and her well-being.
This boy is so deep in love that he’s going to put his feelings on the back burner until he talks to Chitoge to figure out what’s wrong and why she left.
He knows she’s troubled and worried about something incredibly important to her. He doesn’t even know what’s worrying her, but that’s not what’s bothering him. He wants to be her sound board so she can vent and tell him what she’s worried about. He’s worried and down because she’s worried and down.
Look at what Raku said with the image above and the one before it
“….You know how she’s quick to complain about stuff that doesn’t matter at all, but when its important stuff, she has this habit of just piling it up inside her? …Which is why I always have to go ask her about it myself. To be honest it doesn’t matter to me exactly what she’s carrying. I just… when that idiot is troubled by herself I just can’t leave her alone.“
Also look at the progression of the panels. Raku goes from downcast to where his face lights up from just talking about Chitoge. As dense and a tsundere as this boy is he’s 100% a sweetheart and I’m 100% behind this.
Kosaki could figure out from this conversation that Raku loves Chitoge.
There’s also this. Raku is putting his feelings on the back burner because of his concern for Chitoge. Raku feels that finding how why Chitoge left and what is bothering her is far more important that who he will confess to, which really speaks volumes about putting the needs of the person you love above your own feelings.
